WARNING Many environmental variables, including patient physiology and
clinical application, can affect the accuracy and performance of the monitor. The
clinician must verify all vital-signs information prior to patient intervention.

WARNING Always check the patient mode (adult, pediatric, or neonate) when
monitoring a new patient. The patient mode determines default alarm limits and
internal algorithm settings. Make sure the monitor has settings that are
appropriate before monitoring the patient.

Directions for Use Introduction 5

WARNING Make sure Acuity patients, and especially those prone to
arrhythmias, are kept under close surveillance. While monitoring patients with
Acuity, the clinician must review all clinical data before implementing therapy. As
with all computerized arrhythmia analysis systems, Acuity cannot replace skilled
care and proper surveillance by a clinician.

WARNING It is possible for Acuity alarms, alerts, or other events to go
unnoticed if clinical personnel are not present at Acuity or if interruptions occur in
power or system operations. To help reduce this possible occurrence, Acuity
must be installed with redundant power supplies and redundant means of
operator surveillance, such as secondary Acuity Central Stations and hallway
message panels.

WARNING The monitor might not meet its performance specifications if stored
or used outside the specified temperature and humidity ranges.

WARNING Use of respiration monitoring by impedance pneumography can
affect the operation of some pacemakers. If pacemaker operation is affected, turn
off respiration pneumography. (See Figure 61 on page 55.)

WARNING Do not connect more than one patient to a monitor.

WARNING Do not connect more than one monitor to a patient.

WARNING During defibrillation, keep discharge paddles away from the monitor

ECG lead wires, electrodes, any other monitor sensors, and other conductive
parts in contact with the patient.

WARNING Do not operate this product in the presence of flammable
anaesthetics or other flammable substances in combination with air or
oxygen-enriched environments. Failure to observe this warning can result in an
explosion.

WARNING Do not use the monitor in a Magnetic Resonance Imaging (MRI)
suite or a hyperbaric chamber. Such use can cause fire or explosion resulting in
patient injury and monitor damage.

WARNING Do not operate this monitor near equipment that emits strong
electromagnetic or radio-frequency signals. Electronic equipment of this type can
cause electrical interference with monitor operation, which can distort the ECG
signal and prevent accurate rhythm analysis.

WARNING To comply with Federal Communications Commission (FCC) RF
exposure requirements and to avoid exposure to radio-frequency (RF) radiation,
always use the monitor in accordance with the operating conditions and
instructions provided in this manual.

WARNING Pacemaker signals can differ from one pacemaker to the next. The
Association for Advancement of Medical Instrumentation (AAMI) cautions that “in
some devices, rate meters may continue to count the pacemaker rate during

6 Introduction Welch Allyn Propaq LT Vital Signs Monitor

WARNING Use only accessories supplied by Welch Allyn or recommended in
the Welch Allyn Products and Accessories guide (810-0409-XX). Use of any other
accessories can result in inaccurate patient data and damage to the equipment.
Always use accessories according to facility standards and the manufacturer’s
recommendations. Always refer to the manufacturer’s instructions.

WARNING Use of Masimo LNOP sensors/cables will not provide protection in
accordance with IEC defibrillation standards when used with this device.

WARNING Use only ECG cables supplied or specified by Welch Allyn. Use of
any other ECG cables can negate defibrillator protection and can create a risk of
patient injury due to shock.

WARNING Frequently inspect—electrically and visually—all cables, sensors, and
electrode wires. Replace any damaged cables, sensors or wires. Failure to
properly inspect and keep in excellent working order all cables, sensors, and
electrode wires can result in hazards to patients and to equipment failure and
damage.

WARNING Always properly connect the electrosurgery return circuit. Improper
circuit connection can cause current to return through monitor electrodes and
probes, creating a burn hazard for patients.

WARNING Always keep patient motion to a minimum. Motion artifact can cause
inaccurate measurement of patient vital signs.

WARNING Carefully route and secure patient cabling, using the supplied
garment clips. Improperly routed and secured cabling can cause the patient to
become entangled in the cables, creating a strangulation hazard.

WARNING When the patient is wearing the monitor or being transported by
stretcher with the monitor connected, always take care to position the monitor
carrying straps on the patient. Be certain that the straps do not and cannot cross
the neck or throat and cause choking, and the straps do not restrict movement of
the patient’s arms or legs.

WARNING Never use a monitor that is not working properly. If the monitor is not
working properly, patient waveforms might be inaccurate or might not be
displayed.

WARNING If the monitor is damaged, or if you see any indication that the
monitor is not operating properly, disconnect it from the patient. Do not return it
to service until it has been inspected and, if necessary, repaired by qualified
service personnel.

WARNING This wireless medical device was tested and, when used with a
metal-free accessory between the monitor and the patient, complies with FCC
RF Exposure (SAR) guidelines. The use of accessories containing metal may not
ensure compliance with FCC RF exposure guidelines. Specific Absorption Rate
(SAR) is a measurement of radio frequency energy. The FCC permits a maximum
SAR value of 1.6 mW/g. The highest SAR value for this patient monitor, when
worn by a patient in accordance with the directions for use, is 0.560 mW/g.

WARNING High-power radars are allocated as primary users of the bandwidth
between 5.25 GHz and 5.35 GHz and between 5.65 GHz and 5.85 GHz. These
radars can cause interference with this device and can damage this device.

Directions for Use Introduction 11

HIPAA considerations

Each medical facility is responsible for creating and enforcing policies and procedures to
guarantee compliance with the regulations defined in 45 CFR 160-164 of the Health
Insurance Portability and Accountability Act (HIPAA) of 1996.

The Propaq LT Monitor, the Large Color Display Interface, the Propaq LT Monitor
Configuration Utility, and the Propaq LT Monitor AutoPrint Utility incorporate security
features that support your implementation of the HIPAA requirements for ensuring that
patient information is kept private and confidential.

Monitor

• Clinicians can lock the monitor display to prevent the display of patient vital signs. For
patient protection when the monitor display is locked, the display is restored instantly
in the event of a button press (unless button-pad lock-out is enabled), an alarm or an
alert.

• Clinicians can lock the monitor buttons to prevent any unauthorized access to the
monitor controls. To protect the patient when the buttons are locked, access to the
buttons is restored instantly in the event of an alarm or an alert.

• No physiological data transmitted by radio from the monitor is in clear text. All data
sent is encoded using Welch Allyn's proprietary PSI Communications Protocol and
can only be decrypted by a Welch Allyn Acuity Central Station residing on the local
Welch Allyn FlexNet network. By default, data transmitted using the 802.11a
standard is also encrypted using AES (Advanced Encryption Standard).

Configuration utility

The Configuration Utility never contains patient data.

AutoPrint utility

• All patient data is stored in a Welch Allyn proprietary data format which is readable
only by machine.

• All patient data is deleted from the PC when it is sent to the printer.

Overview of monitor operation

Turning on the monitor

The monitor runs through an operational self-test each time it is powered on. Always
verify that it follows the power-on sequence shown below. When Step 3 completes as
described, the monitor has verified that the visual and audible alarm indicators are
working properly. If Step 4 does not complete as described, remove the monitor from
service and have it examined by a qualified service person.

To turn on the monitor

1. Press and hold until a tone sounds.

2. A tone sounds as the green, yellow, and red lights turn on and off. This occurs twice.

3. The splash screen appears, identifying the product and displaying the message
“Diagnostics in progress”. The green light turns on and off quickly while the low tone
sounds, the yellow light turns on and off quickly while the medium tone sounds, and
the red light turns on and off quickly while the loud tone sounds.

Utility to configure the monitor” on page 114).

• A new configuration is downloaded from Acuity.

About the charging/communications cradle

When the charging/communication cradle (the cradle) is attached to AC power (or to
vehicle DC power) and the monitor is seated in the cradle, the cradle does the following:

• Recharges the monitor battery, whether patient monitoring is occurring or not.

• Powers the monitor, conserving the charge on the monitor battery.

• (If the cradle has the USB data transfer option) enables data transfer between a
PC and a monitor. See “About the USB data transfer option” on page 15.

Cradle

The cradle is intended to hold the monitor when the patient is in bed or is other wise
stationary. The cradle can sit on a flat surface near the patient or attach to the bed rail
(using the bed-rail hook).

If the monitor is in the cradle and the AC power adapter is connected to the cradle, the
monitor runs on AC power rather than battery power. This keeps the monitor battery at full
charge so that the monitor can then run on battery power when it is removed from the
cradle to accompany the patient away from the bed.

The cradle can be connected to AC power at all times, whether the monitor is present or
not.

About the USB data transfer option

A cradle configured with the optional USB communication port and connected to a PC
with the Propaq LT Configuration Utility and the Propaq LT AutoPrint Utility can be used
for the following:

• Creating custom monitor configurations on the PC and downloading them to any
number of monitors. (See “Monitor configuration” on page 101.)

• Uploading the configuration file from the monitor to the PC.

• Uploading patient data from the monitor to the PC for printing. (See “Printing

patient data” on page 95.)

Setting up the cradle

1. Place the cradle on a table or shelf, or hang it on a bed rail.

WARNING Place the cradle so that it cannot fall on the patient.

Caution Locate the cradle near the patient but not so close that it interferes

with patient care.

Certain properties of each display type can also be configured. See “Display Format” on
page 127.

To view a tabular display if no tabular trends format is specified

1. Access the Setup menu. (See “To access the setup menus” on page 35.)

2. Highlight Trends and press .

Note

All valid display configurations include at least one waveform format.

Timing out the display and the back light

To conserve battery run life, the monitor display and the back light can be configured to
turn off if no operator activity (that is, a button press) is detected for a specified number of
minutes.

• When the display is off, no patient data is visible.

• When the back light is off, patient data is visible only under direct light.

If the display and the back light are turned off due to a time out, they turn on again
immediately when an alarm or alert occurs or, if the buttons lock-out is not
enabled, when you press any monitor button.

Note

The monitor configuration determines whether the time-out feature is enabled or
disabled, and defines the default time-out period if it is enabled. If the feature is enabled in
the configuration, you can temporarily change the time-out period or disable the time out
through the Setup -> Timings menu.

Directions for Use Overview of monitor operation 21

Locking out the display, back light, and buttons

If lock-outs are enabled, you can lock out one or more of the following elements:

Buttons To prevent unauthorized use

Back Light To extend the battery run life

Display To prevent unauthorized viewing of patient information

The monitor configuration defines which of these, if any, can be locked out. For
information on enabling or disabling lock-outs for these elements, see “Monitor

configuration” on page 101.

To lock out the configured elements

Hold down , , and simultaneously for 5 seconds.

To unlock the configured elements

Hold down , , and simultaneously for 5 seconds.

Note

Alarms and alerts immediately unlock any locked elements.

Large color display interface

Using the Large Color Display Interface (‘interface box’) optional accessory, you can
display patient vital signs from the monitor on a full-size screen. This screen is typically
mounted on a wall within one or two meters of the patient’s bed. It receives video signals
from the cradle via a VGA cable.

Large color display configuration options

• If the interface box is mounted on the large screen (Figure 15), the screen must be
within about 3 meters of the cradle.

• If the interface box is mounted on the cradle (Figure 16), the distance between the
box and the screen is limited by the length of the VGA cable.

• If the interface box, the cradle, and the large screen are mounted together (Figure 17),
the distance from them to the patient’s bed is limited by the length of the SpO
sensor cable, the ECG cable, and the NIBP air hose (whichever is shortest).

Note

Note

The various configurations are not interchangeable. Each requires a unique
combination of screws, USB and power cables, and VGA cable.

If the interface box is attached to the cradle, the bed rail hook cannot be used.

When the interface box is attached to the cradle, the default power and USB cables
(references A and B in Table 6, “Cables and AC power adapter”) connect the interface box
and the cradle. (See Figure 17 on page 23.)

If the interface box and the cradle are not attached, longer cables—references C and D in

Table 6, “Cables and AC power adapter”—are used.

The AC power adapter (reference E) is shipped with the cradle.

Note

The AC power adapter used with the Propaq CS monitor or the Propaq Encore
monitor will not power the interface box.

When the interface box is not used, the AC power adapter is attached to the cradle. When
the interface box is used, the AC power adapter is connected to it and not to the cradle.

When you enter Demo mode, the monitor is in ‘Demo mode low’. In this mode, the
simulated vital signs of the patient are steady and do not cause any alarms at the default
alarm limit settings. You can explore the monitor displays and menus, and you can change
the same settings and values in Demo mode that you can change in normal mode.

In Demo mode low, if you adjust the alarm limits to put the simulated patient’s vital signs
out of limits, the monitor simulates an alarm condition. Another way to simulate an alarm
condition is to switch the monitor to Demo mode high, which uses higher numeric values.

Directions for Use Overview of monitor operation 43

Transporting the monitor with the patient

An ambulatory patient can wear or carry the monitor using the wearable strap or the
patient carry strap (optional accessories). Medical personnel can use the transport
stretcher carry strap to keep the monitor with a patient during stretcher transport.

WARNING When the patient is wearing or carrying the monitor, carefully route

any patient cabling to reduce the possibility of patient entanglement or
strangulation. Use the supplied garment clips to secure the cable properly.

WARNING When positioning straps on the patient, make sure the straps do not
entangle the patient’s neck or cause choking.

WARNING Make sure the straps do not restrict the movement of the patient’s
limbs or create a hazard for the patient when the patient is walking or moving.

WARNING Never use a strap to carry or pick up both the monitor and the cradle.
The straps are not intended to support, and cannot support, the combined weight
of the monitor and the cradle.

To attach the wearable strap

WARNING Do not put the wearable strap on the patient while the patient is in
bed. The intended use of the wearable strap is to keep the monitor—without the
cradle—with the patient when the patient is ambulatory.

Figure 40. Wearable strap

1. Place the wearable strap on the sitting or standing patient and adjust all components
for a comfortable, secure fit (Figure 40 left).

2. Connect the wearable strap securely to the monitor strap mounts (Figure 40 right).

3. Carefully arrange the strap and the monitor on the patient to avoid bruising or other
skin injuries.

44 Overview of monitor operation Welch Allyn Propaq LT Vital Signs Monitor

To use the patient carry strap

WARNING Do not use the patient carry strap to lift or carry both the monitor and

the cradle. The patient carry strap is not intended to support (and cannot support)
the weight of both the monitor and the cradle. Attempting to carry both the
monitor and the cradle with a patient carry strap could lead to patient injury and to
damage to the monitor and the cradle.

1. Remove the monitor from the cradle.

2. Detach the monitor cables from any accessories.

3. Verify that all cables are disentangled from the bed and any bedside tables.

4. Connect the ends of the carry strap to the strap mounts on the monitor.

Note

Be sure that each end of the carry strap snaps into place.

Figure 41. Patient carry strap

To use the transport stretcher carry strap

1. With the monitor facing away from the stretcher and the patient, attach one end of
the strap to a monitor strap mount.

2. Run the monitor strap under the stretcher restraint straps, near the patient’s waist.

3. Attach the other end of the strap to the other strap mount.

Standalone monitoring

Overview

The monitor is available in standalone models (802LT0N and 802LT0S) and in wireless
models (802LTAN, 802LTAS, 802LTRN and 802LTRS).

This chapter describes the operation of the standalone monitor and of the wireless
monitor when it is not in communication with the Welch Allyn Flexnet

®

Acuity

Central Station.

About the Model 802LT0N and 802LT0S (standalone) monitors

The model 802LT0N and 802LT0S monitors operate in standalone mode. They measure
and display vital signs, store patient data, and locally indicate alarms and alert conditions.

• The configuration of the monitor is not affected by Acuity.

• The vital signs stored by the monitor are not sent to Acuity.

• Alarms and alerts generated by the monitor do not appear on Acuity.

• Alarms and alerts generated by Acuity do not appear on the monitor.

• Acuity does not update the monitor time and date settings.

Monitoring ECG and Resp

Overview

Note

In this manual, lead refers to an ECG electrode or lead wire, and Lead refers to a
waveform source.

You can monitor heart signs (ECG) and respiration rate (Resp) using either a 3-lead or a
5-lead ECG cable. Using a 3-lead cable, you can display one signal waveform for lead I, II,
or III. Using a 5-lead cable, you can display either one or two signal waveforms (I, II, III, V;
and if enabled in the configuration, aV

, aVL, or aVF). You can also display the SpO2 or

R

Resp waveform in place of an ECG waveform.

WARNING Always monitor and set alarms for SpO2 when using impedance
pneumography to monitor respiratory function.

WARNING When monitoring respiration via impedance pneumography, always
select the ECG Lead with the most prominent QRS complex. The monitor rejects
cardiovascular artifact, but this function depends upon accurate ECG R-wave
detection.

WARNING Do not place the monitor near another respiration monitor. Resp
measurement frequencies can cause mutual interference.

WARNING Do not perform impedance pneumography on paced patients.
Pacemaker pulses can sometimes be falsely counted as breaths.

WARNING Always keep patient motion to a minimum. Motion artifact can cause
incorrect readings of breath rate or heart rate.

WARNING If a disconnected lead is too close to other electrical devices, it can
cause a false heart rate, a false respiration rate, or a failure to display a “Lead Fail”
message.

WARNING The monitor displays + + + for HR numerics between 301-350 beats
per minute. For heart rates above 350 beats per minute, it might display
incorrectly low heart readings, due to intermittent picking of R-waves.

WARNING The monitor does not provide internal arrhythmia analysis; therefore,
arrhythmias can cause the monitor to display inaccurate heart rates.

Directions for Use Standalone monitoring 51

WARNING Motion artifact can cause the monitor to display inaccurate heart
rates. Minimize patient motion whenever possible.

WARNING (1) During a surgical procedure, do not use small ECG electrodes.
(2) Select ECG electrode attachment points remote from the surgical site and
remote from the electrosurgical return electrode. (3) Use electrosurgical return
electrodes with the largest practical contact area. (4) Assure proper application of
the electrosurgical return electrode to the patient.

High-intensity radio-frequency (RF) energy from external sources, such as an
improperly connected electrosurgical unit, can induce heat into electrodes
and cables, which can cause burns on the patient and can lead to
measurement errors.

WARNING Make sure the patient mode is correct. Incorrect patient mode can
result in inaccurate heart rate readings and inappropriate alarm settings.

WARNING Always use the provided garment clips to route ECG cables away
from the patient’s head.

WARNING Use only accessories listed in the Welch Allyn Products and
Accessories guide (810-0409-XX).

Note

WARNING Never use ECG cables with loose or faulty detachable lead wires.

These can cause erratic behavior of the ECG and respiration waveforms due to
intermittent ECG lead wire connections.

WARNING Resp is derived from the same leads as the ECG channel, so the
monitor determines which signals are cardiovascular artifact and which signals are
a result of respiratory effort. If the breath rate is within five per cent of the heart
rate or is a multiple or submultiple of the heart rate, the monitor might ignore
breaths and trigger a respiration alarm.

Caution Never use an ECG cable longer than 10 feet (3 meters) including
extensions. If you use an ECG extension cable with an ECG cable longer than
4 feet, the monitor acts as though no ECG cable is connected.

Caution To protect the monitor from damage during defibrillation or
electrosurgery, for accurate ECG information, and for protection against noise
and other interference, use only ECG electrodes and cables specified or supplied
by Welch Allyn (these cables have the required current-limiting resistors). Follow
recommended application procedures.

The monitor contains type CF fully isolated patient-connected circuitry, but it is
not intended for direct application on a patient’s heart.

Severe artifact and interference (such as defibrillation interference) can cause the
waveform to move off of the display for a few seconds before it is restored.

Impedance pneumography (Resp) is not recommended for use with
high-frequency ventilation.

The monitor counts as breaths any respiratory efforts larger than twice the
background cardiovascular artifact.

Note

Monitoring ECG

1. Inspect the ECG cable. Replace it if it shows any signs of wear, breakage, or fraying.

2. Plug the cable into the monitor.

3. Select electrode sites on the patient, choosing flat areas and avoiding fatty or bony
areas and major muscles.

Figure 54. ECG leads - actual placement

Use only silver/silver chloride electrodes. Other electrodes, such as stainless
steel electrodes, squeeze-bulb electrodes, or electrodes with dissimilar metals,
are subject to large offset potentials due to polarization. Other electrodes can also
have slower recovery time after the application of defibrillator pulses.

4. Shave or clip the hair from the electrode sites.

5. Thoroughly clean the skin, using soap and water, isopropyl alcohol, or skin preparation
pads, and lightly rub it dry.

Caution To protect the patient from allergic reactions to electrodes, refer to the
electrode manufacturer’s directions for use.

6. If you are using gelled electrodes, verify that the electrode expiration date has not
passed and that the gel is intact and not dried out.

If you are not using gelled electrodes, apply a mound of gel (1/4-inch to 1/2-inch, or

0.6-cm to 1.3-cm) to each electrode contact area.

The locations of the circles displayed on the monitor (Figure 55) for each lead are
fixed, and do not indicate the exact placement of the electrodes on the patient.

If the monitor detects that some lead wires are not connected, it displays an “ECG
Fault” equipment alert and a chest diagram indicating the location of the
disconnected lead or leads. If the disconnected lead(s) invalidate the Lead used for
HR determination, then the monitor reassigns, if possible, the Lead used for HR. If
the reassignment succeeds, the monitor then displays another equipment alert with
the message “ECG Lead changed”.

About pacemakers and ECG monitoring

If the patient being monitored has a pacemaker, the monitor detects and can indicate the
occurrence of pacemaker signals. If the Pacer Indicator setting is ON, the monitor displays
and prints vertical dashed lines to indicate detected pacemaker signals. If Pacer Indicator
is OFF, the monitor continues to detect the pacemaker signals but does not display or
print the pacer markers.

WARNING Signals differ between pacemakers. The Association for
Advancement of Medical Instrumentation (AAMI) cautions that “in some devices,
rate meters may continue to count the pacemaker rate during occurrences of
cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms.
All pacemaker patients should be kept under close or constant observation.”

WARNING Use of respiration monitoring by impedance pneumography can
affect the operation of some pacemakers. If pacemaker operation is affected, turn
off respiration pneumography. (See Figure 61 on page 55.)

WARNING Always use fresh ECG electrodes and make sure the ECG cable lead
wires make good connections. The presence of pacer-like noise can cause the
displayed heart rate to be erratic even though the ECG trace might look
undistorted with the pacer indicator off.

To enable or disable the display of pacer indicators

1. Access the Setup menu. (See “To access the setup menus” on page 35.)

2. Highlight ECG.

Note

If the pacemaker signal is strong enough, the monitor displays it as a waveform
spike. This is true with Pacer indicator ON or OFF.

In accordance with the Pacer Pulse Rejection specification (“Pacer pulse

rejection” on page 143.), pacemaker pulses are not counted as heartbeats

whether Pacer Indicator is On or Off.

Noise on the ECG signal might be detected as pacer signals, causing the pacer
indicator to appear on the display. If you do not need to indicate pacemaker
signals, turn off the pacemaker indicator for a better ECG waveform display.

Improving the waveform display

If the power source filter is off, noise from the power source can cause an unclear or
noisy waveform.

To change the power source filter to reduce noise

1. Access the Setup menu. (See “To access the setup menus” on page 35.)

2. Highlight ECG.

Verify that the setting for Power source filter is correct for the power source in your

WARNING Accurate measurements of oxygen saturation, when derived from
pulse oximetry, depend to a great extent on patient condition and proper sensor
placement. Patient conditions such as shivering and smoke inhalation can result in
erroneous readings. If you believe a measurement might be inaccurate, verify it
using another clinically accepted measurement method, such as arterial blood gas
measurements using a co-oximeter.

WARNING Use only SpO

WARNING Interfering substances: Carboxyhemoglobin can erroneously
increase readings; the level of increase is approximately equal to the amount of
carboxyhemoglobin present. Methemoglobin and other dysfunctional
hemoglobins can also cause erroneous readings. Further assessment beyond
pulse oximetry is recommended. Intravascular dyes, or any substances
containing dyes, that change usual arterial pigmentation can cause erroneous
readings. Darkly pigmented skin can adversely affect SpO

readings.

2

WARNING For a premature infant, high oxygen levels might predispose the
infant to develop retinopathy. Therefore, the upper alarm limit for oxygen
saturation must be carefully selected in accord with accepted clinical standards
and considering the accuracy range of the monitor.

Caution If liquid gets into the SpO2 connector cavity, discontinue SpO2
monitoring until the liquid is removed and the cavity is dry.

1. Inspect the SpO2 cable. Replace it if it shows any signs of wear, breakage, or fraying.

2. Plug the cable into the sensor and the monitor.

Each SpO

sensor is intended for application to a specific site and site size on the

2

patient. To obtain optimal performance, use the right sensor and apply it as instructed
by the sensor manufacturer.

3. Clean the application site. Remove anything, such as nail polish, that could interfere
with the operation of the sensor.

4. Attach the SpO

sensor to the patient according to the manufacturer’s directions for

2

use, observing all warnings and cautions.

5. Confirm that the monitor displays SpO

data within a few seconds of being

2

connected to the patient.

• If ambient light is too bright, shield the sensor site with opaque material. Failure

to do so can result in inaccurate measurements. Light sources that can affect
performance include the following:

- surgical lights (especially those with a xenon light source)

- bilirubin lamps

- fluorescent lights

- infrared heating lamps

- direct sunlight.

• To help reduce unnecessary SpO

simultaneously, place the NIBP cuff and the SpO

• The pulse signal can disappear if any of the following conditions exists:

- the sensor is too tight

- ambient light is too bright

- an NIBP cuff is inflated on the same limb as the sensor

- arterial occlusion occurs near the sensor

- the patient is in cardiac arrest or shock

- the patient has hypotension, severe vasoconstriction, severe anemia, or

About the Masimo SpO2 display

The Masimo SpO2 option provides the following additional features and indicators.

The monitor (models 802LTAS, 802LTRS and 802LT0S) must be configured
specifically to display the Masimo parameters.

Signal IQ (SIQ) (Signal Identification and Quality indicator) A horizontal line

below the SpO
the relative reliability of the oxygen saturation readings.
(Higher spikes indicate greater reliability.)

Perfusion Index (PI) An assessment, expressed as a percentage between 0.02

and 20, of the relative pulse strength at the monitoring
site.

FastSAT™ The tracking of rapid changes in arterial oxygen saturation.

Sensitivity Normal, APOD, and Maximum.

Directions for Use Standalone monitoring 63

Normal For typical monitoring.

APOD For monitoring when the probe is likely to detach from the

patient because of wet skin, motion, or other unusual
circumstances.

Maximum For monitoring patients with extremely low perfusion.

Averaging Time The period (in seconds) over which multiple SpO2

measurements are taken and a result is derived.

Monitoring blood pressure (NIBP)

WARNING Always use a properly fitting cuff, placing it carefully on the patient
according to the instructions presented below. Failure to fit and locate the cuff
correctly can lead to inaccurate pressure readings.

WARNING During monitoring, periodically observe the patient’s limb to make
sure that the circulation is not impaired for a prolonged period. Prolonged
impairment of circulation or improper cuff placement can cause bruising.

WARNING Do not use the monitor to simultaneously measure NIBP on one
patient and monitor ECG on another patient.

WARNING If an NIBP measurement is suspect, repeat the measurement. If you
are still uncertain about the reading, verify it using another method.

WARNING Do not take NIBP measurements during cardiopulmonary bypass.

WARNING When monitoring NIBP, match the monitor patient mode to the NIBP

cuff. For neonates, set the monitor to Neonatal Mode unless the circumference
of the limb is too large for the cuff. In that case, use the Pediatric Mode. Be
aware, however, that the maximum cuff inflation limits are based on the patient
mode, not the cuff; the maximum cuff inflation limits for Pediatric Mode are
greater than for Neonate Mode. (See “NIBP” on page 147 for values.)

Caution Pulse-rate measurements generated through the blood pressure cuff
or through SpO
measurements generated through ECG or through manual palpation.

When the monitor is powered on, the default cuff inflation pressure is based on the
patient mode. (See “Default inflation pressure” on page 147.) After an NIBP
measurement occurs, the monitor adjusts the inflation pressure to optimize subsequent
NIBP measurements.

Note

Always cycle the monitor power before you begin to monitor another patient.

Normal physiological pressure variations affect NIBP measurements from reading
to reading.

If the monitor is in Adult mode and a neonate cuff is connected to the monitor,
the monitor generates an equipment alert.

If the battery charge is low and the monitor is not in the cradle, the battery icon
indicates low battery and NIBP monitoring is disabled.

To monitor blood pressure

1. Select cuff size based on limb circumference. Use only hoses and cuffs listed in the
Welch Allyn Products and Accessories guide.

2. Squeeze all the air from the cuff before placing the cuff on the patient.

3. Place the cuff on the limb, as near heart level as possible.

Figure 70. Cuff placement

Cuff applied evenly and snugly. The
center of the cuff is at heart level,
and the bottom edge is one inch (2.5
cm) above the antecubital fossa.

Possible cuff placements for neonates

• The cuff must fit snugly without being uncomfortably tight.

• The hose must be free of kinks and not pinched.

4. Align the point where the tubing connects to the cuff over the brachial or other
appropriate artery.

Note

If you are simultaneously monitoring blood pressure and SpO

Setup

• If you need to stop the reading and vent the cuff at any time during the

measurement, press .

• If the monitor cannot get a valid NIBP reading, it displays the message

‘NIBP retry in progress’ in the upper left corner of the screen. Then, depending on
settings and patient mode, the monitor attempts one or two more
measurements. If the retries fail to produce a valid reading, the monitor displays
an NIBP error message.

Note

For every inch the cuff is placed above the heart, add 1.9 mmHg (0.253 kPa) to the
displayed NIBP reading. For every inch below the heart, subtract 1.9 mmHg
(0.253 kPa).

8. If motion artifact such as shivering or coughing interferes with NIBP readings, do the
following:

• Position the patient’s limb away from the body so that the applied cuff is not in

contact with the patient’s body or any other object (such as a bed rail). Keep the
cuff as close to heart level as possible.

• Verify that the Smartcuf filter is ON. (See “Improving NIBP accuracy with

Smartcuf” on page 66.)

• Verify that the ECG leads are properly connected to the patient, and monitor ECG

during NIBP. (ECG monitoring is required for Smartcuf.)

66 Standalone monitoring Welch Allyn Propaq LT Vital Signs Monitor

Note

Note

The message ???/???/(???) in an NIBP TREND display or printout indicates that
the monitor could not complete an NIBP measurement during that period.

On-demand NIBP readings (manual or turbo) are delayed by 8 seconds if they are
started while the monitor is in a power-saving mode such as display time-out.

Improving NIBP accuracy with Smartcuf

Many factors can adversely affect an NIBP measurement: cardiac arrhythmias, sudden
changes in blood pressure, patient motion such as convulsions or shivering, sudden cuff
movement, vibration, vehicle motion, or a weak pulse. The Smartcuf feature increases
NIBP measurement accuracy in the presence of moderate motion artifact or diminished
pulses.

s

Note

To enable Smartcuf

1. Simultaneously monitor ECG and NIBP.

2. Access the Setup menu. (See “To access the setup menus” on page 35.)

3. Highlight NIBP, highlight Smartcuf, and enable the Smartcuf filter.

Smartcuf can function only when ECG is being monitored.

If Smartcuf is enabled and motion artifact is so severe that it still affects measurement
accuracy, the measurement is marked with the symbol on the display. During certain
types of arrhythmias and other situations where a good ECG signal cannot be obtained,
consider disabling Smartcuf, as follows:

To disable Smartcuf

1. Access the Setup menu.

2. Highlight NIBP, highlight Smartcuf, and disable the Smartcuf filter.

Taking automatic NIBP readings

In the Auto NIBP mode, for intervals shorter than 5 minutes, the monitor immediately
begins taking NIBP readings at the specified interval. For intervals of 5 minutes or longer,
the readings begin when the time of day is a multiple of the interval. (If the interval is 15
minutes, for example, then the readings begin at 00, 15, 30, or 45 minutes after the hour.)

To start automatic NIBP readings

1. Select and apply the appropriate NIBP cuff and hose. (“Monitoring blood pressure

(NIBP)” on page 63.)

2. Highlight NIBP and press .

3. Highlight NIBP Mode and select Auto.

4. Highlight Auto Interval (min) and select an interval.

Note

After you invoke an automatic NIBP, expect a delay before the monitor starts the
first measurement. The delay can be as long as the interval selected.

Directions for Use Standalone monitoring 67

To stop automatic NIBP readings

1. Highlight NIBP and press .

2. Highlight NIBP Mode and select Manual.

Taking NIBP readings using Turbo mode

In Turbo mode, the monitor starts an NIBP reading and then takes as many more readings
as possible within five minutes.

To use the Turbo mode

1. Select and apply the NIBP cuff and hose. (“Monitoring blood pressure (NIBP)” on
page 63.)

2. Highlight NIBP and press .

3. Highlight NIBP Mode and select Tu r b o .

Note

To end the Turbo mode

If you cycle the monitor power, NIBP returns to auto mode.

Press or select NIBP Mode Manual. The monitor returns to manual NIBP
measurement mode.

NIBP measurements in power-saving mode

When a manual or turbo NIBP activity awakens the monitor from power-saving mode
(“Power saving” on page 42), cuff inflation pressure is reset to default levels and cuff
inflation is delayed for up to 8 seconds.

NIBP disabled when the battery is low

If the battery is low and the monitor is operating on battery power, NIBP functions are
disabled and the monitor displays the message “NIBP off. Low battery.”

If you attempt to start an NIBP measurement during a low-battery condition, the monitor
displays an equipment alert with the message “Low battery. NIBP disabled.”

Note

Inserting a monitor into a powered cradle during a low-battery condition
immediately enables NIBP monitoring.

with Acuity

About wireless monitoring

The model 802LTAN, 802LTAS, 802LTRN and 802LTRS wireless monitors can operate
either in standalone mode or in communication with a Welch Allyn Acuity Central Station.
(See “Standalone monitoring” on page 45.)

While the wireless monitor is connected to the FlexNet network, patient data gathered by
the monitor is continuously stored at Acuity. At the Acuity station you can access this
patient information and perform administrative functions, including the following:

• Admit, transfer, and discharge a patient in the Acuity unit.

• Edit the patient description (name, physician, and so on).

• Review and print patient data such as trends and waveforms.

For more information about Acuity and the FlexNet wireless network, refer to Acuity
directions For use.

For Model 802LTAN and 802LTAS monitors, the radio, by default, authenticates against
the WA RADIUS server running on an Acuity Central Station. If the hospital IT department
requires a different authentication/encryption solution, then the monitor, using the factory­default radio configuration, cannot connect to the network.

WARNING When monitoring a patient who has a pacemaker, position the
monitor to maintain a minimum distance of 6 inches (16 cm) between the monitor
and the pacemaker. If you have any reason to suspect that the monitor is

interfering with the pacemaker, immediately turn the monitor off and
provide appropriate patient care. The Health Industry Manufacturers

Association recommends this minimum distance (6 inches or 16 cm) between a
hand-held wireless radio and a pacemaker, which is consistent with the
independent research by, and recommendations of, Wireless Technology
Research.

WARNING When considering a treatment protocol that involves wireless
communication of patient data, be aware of this limitation:

When the monitor is not connected to the network by wireless connection:

Acuity does not receive patient alarms or alerts from the monitor.

Acuity does not perform arrhythmia and ST analysis on patient data and
therefore does not generate related alarms.

WARNING If you establish a USB link to any active host while the monitor is in
network communication with Acuity, the wireless connection is lost.

Note

When the monitor is used in Canada:

To provide maximum shielding (to prevent radio interference to the licensed
service), the monitor is intended to be operated indoors and away from windows.
Radio equipment (or its transmit antenna) that is installed outdoors is subject to
licensing.

Afin de fournir un écran de blindage maximal (pour empêcher que cet appareil
cause du brouillage au service faisant l’objet d’une licence), l’appareil doit être
utilisé à l’intérieur et devrait être placé loin des fenêtres. Si le matériel (ou son
antenne d’émission) est installé à l’extérieur, il doit faire l’objet d’une licence.

Establishing communication with Acuity

If the monitor is enabled for communication with Acuity, communication is established
automatically whenever the monitor is within range of the network.The monitor always
indicates the status of the connection:

Figure 75. Connection status indicator

The monitor is not enabled for communication with Acuity.(blank)

The monitor is communicating via USB cable with a PC.

The monitor is associated with the network and is
communicating with Acuity.

(Flashing) The monitor is associated with the network but
is not communicating with Acuity.

(Continuous) The monitor is not associated with the
network and is not communicating with Acuity.

HALL, ROBERT E.

Verify that the monitor, within a minute or two, displays to indicate that the connection
to Acuity has been established.

Upon connecting to the network, the monitor uploads the following data to Acuity:

• Patient information and trends stored at the monitor before the network

connection was established

• Monitor settings

At the same time, Acuity downloads some configuration settings to the monitor. (See

“About Acuity-defined configuration” on page 102.)

Directions for Use Monitoring in communication with Acuity 73

Monitoring a patient outside of network range

Monitoring continues locally when the monitored patient goes outside of the range of the
network. The monitor provides local Resp, NIBP, HR/PR and SpO
alerts. The following also happens:

• An alert occurs at Acuity with the message DROPOUT.

• An alert occurs at the monitor with the message Check Acuity/network

connection.

• The monitor emits audible alert tones.

• The appropriate caregiver presses to acknowledge the alert.

WARNING When the monitor moves out of range of the Acuity network,
communication with Acuity is broken immediately, stopping the communication
of patient vital-signs data. If the monitor is out of range of the Acuity network for
several minutes, the radio enters a low-power state. When the monitor is again
within range of the Acuity network, it can take as long as three minutes to restore
communication with Acuity and resume the communication of patient vital-signs
data.

alarms or equipment

2

Note

When the monitored patient is again within network range, the monitor reconnects to the
network and wireless monitoring resumes.

Note

When the monitor is outside of network range, battery operating time is reduced.

When communication with the network is re-established, trends data is uploaded
to Acuity but snapshot data is not.

About Acuity message menus

When the monitor first establishes communication with Acuity and the clinician selects to
start a new patient, the monitor presents a series of screens to determine the location
(unit and room number) and the name and ID number of the monitored patient. If the
patient is already known to Acuity, you can select the identifying information from a series
of lists. If the patient is new to Acuity, you provide the information.

If the clinician is continuing to monitor the same patient, these Acuity message menus
are not presented.

Note

First, the monitor displays a list of units. Highlight the unit for this patient and press .

Some of these menus can contain lists that are too long to fit on the screen. To
view or highlight list items that are not on the screen, press or repeatedly
as needed scroll the list.

Alarms and alerts

Overview

An Alarm warns of a patient condition, such as a vital-sign reading that is outside of
acceptable limits. When an alarm occurs, the red light on the monitor flashes and the
numerics of the violating alarm limits on the display turn red. If tones are not suspended,
the alarm tone sounds.

An Alert warns of an equipment condition, such as a low battery or a detached lead.
When an alert occurs, the yellow light on the monitor flashes and a message describing
the error condition appears on the display. If tones are not suspended, the alert tone
sounds.

Alarms have priority over alerts. If an alarm and an alert are detected simultaneously, the
monitor notifies you of the alarm. It then notifies you of the alert only if the alert condition
still exists after the alarm condition is removed.

Silencing an alarm or alert tone

A tone sounds whenever the monitor detects an alarm or alert condition.

To silence the currently sounding tone for 90 seconds

1. Pr e s s .

Note

Silencing the tone does not affect the other alarm or alert indicators.

• The red light (alarm) or the yellow light (alert) flashes.

• After 90 seconds, if the condition is not corrected, the tone starts again.

• If the condition is corrected within 90 seconds of silencing the tone, the monitor
resets the tones for the next alarm or alert.

If a new alarm or alert condition occurs while an earlier alarm or alert is silenced, the
tone sounds again.

2. Check the patient and provide appropriate care.

3. Press to silence the audible tone for 90 seconds at the monitor and at Acuity.

• Silencing the audible tone does not remove visual alarm or alert indications.

• Silencing the audible tone causes an alarm or alert suspend at Acuity.

• When the alarm or alert condition is corrected, all alarm or alert indicators cease
and all alarms are immediately rearmed.

4. After caring for the patient, verify that alarm limits are enabled and correctly set.

WARNING If you turn off or modify any alarm limits while responding to an
alarm, restore those alarm limits before you resume monitoring.

Suspending the alarm tone

If this feature is enabled in the monitor configuration (See “Monitor configuration” on
page 101), you can suspend all alarm tones for all parameters—preventing the alarm tone
from sounding if an alarm condition occurs—while monitoring a patient. If an alarm
condition occurs while the alarm tones are suspended, the monitor presents visual alarm
indicators but does not sound the tone.

In the monitor configuration, the alarm tone suspension period can be set to Disabled, to

Always On, or to a period: 90 sec or 2, 3, 4, 5, 10, 15, 30, or 60 minutes.

Note

The factory default suspension period is 4 minutes.

• If it is configured to Disabled, you cannot suspend the alarm tone at the monitor.

Changing alarm limits

At the monitor

Typically, each institution determines the appropriate alarm limits for adult, pediatric, and
neonatal patients and then configures the monitor with those alarm limits before putting
the monitor into service. These become the default alarm limits for the monitor—the
alarm limits used each time the monitor is powered on.

The configured alarm limits remain in effect until the monitor configuration is changed.
However, you can temporarily change the current patient’s alarm limits.

To temporarily change alarm limits for the current patient

At Acuity

1. Highlight the vital sign for which you want to set custom limits.

2. Press .

3. Highlight the limit you want to change.

4. Set a new alarm limit.

About ParamSet

Using ParamSet, you can quickly widen the alarm limits by a configured percentage
(relative to the patient’s alarming reading) for any vital sign.

For information about ParamSet, see “ParamSet Settings” on page 131.

Responding to an alarm

An alarm condition is indicated on the monitor in the following ways:

• The RED indicator (rightmost of three) above the display screen flashes.

• The numerics for the vital sign in alarm are displayed in RED.

• If alarm tones are not suspended, the alarm-tone sequence sounds repeatedly—3
short tones, a short pause, 2 short tones, and a long pause.

Responding to an alert

An alert condition (“Over view” on page 79) is indicated on the monitor in the following
ways:

• A flashing yellow light above the monitor display.

• A yellow alert message on the monitor display (for example, NO ECG CABLE
DETECTED).

• Repeated sounding of the alert-tone sequence (if tones are not suspended): 3 long
tones and a pause.

The patient mode setting is incorrect or the wrong hose or
cuff is being used for the current patient mode.

The monitor periodically calibrates (zeroes) the NIBP
channel to make sure it can properly make NIBP
measurements. No NIBP monitoring can be done until the
calibration is completed. Other normal monitor operation
continues during NIBP calibration.

Motion is detected during a periodic NIBP calibration.
Minimize patient motion or motion on the cuff, or
disconnect the cuff. Motion-generated noise on the
pressure transducer can cause the calibration to continue
indefinitely.

The battery is too far discharged to operate the NIBP
channel. Insert the monitor into a powered cradle.

Have the monitor serviced.

A hose is kinked or a neonate hose is detected in the adult
patient mode. Check the hose and the patient mode
selection.

The monitor has detected too much artifact to allow
accurate readings. Take steps to reduce artifact. Position
the patient’s limb away from the body so the applied cuff is
not in contact with the patient’s body or any other object
such as a bed rail.

The monitor detects a network communication problem.

The monitor detects a problem in communication with the
cradle. Detach and reattach the USB cable.

You attempted to select the Name, ID, or Rm field on an

Battery Too Low.
Shutting down.

The monitor battery charge is low, and the monitor will shut
down in 30 minutes or less. Insert the monitor into the
cradle. If no cradle is available, find an alternative method
of monitoring the patient before the monitor shuts down.

The monitor battery charge is very low; the monitor will shut
down in 5 minutes or less. Insert the monitor into a cradle or
find another way to monitor the patient before the monitor
shuts down.

The monitor battery charge is too low to support monitor
function. Monitor operation can continue only after the
battery is recharged or replaced or until the monitor is
inserted in a powered cradle.

example: In Figure 90, the data was measured at “1 Sec after” 14:34:58.

5. To view the waveform and the numeric data for a specific time within the 21 seconds
of data, highlight 1Secafter and then use or scroll the display to the desired time.
For example, to see the vital signs taken five seconds after the trigger point of the
snapshot, highlight 1 Sec after and press and hold as needed to increment the
display to 5 Sec after.

Overview

Printing patient data

You can print patient data in two ways.

• If the monitor is in communication with an Acuity Central Station, press to print
vital signs at the Acuity system printer.

• If a PC with the Autoprint Utility is connected to a cradle with the USB option, you
can print directly to a printer connected to the PC simply by inserting the monitor
in the cradle.

This chapter tells you how to print with the Autoprint Utility.

The AutoPrint utility uploads from the monitor to the PC, either manually or automatically,
trend data and snapshots stored by the monitor for the current or most recent patient.
The PC then prints the data on the configured laser printer.

Note

Note

Use only a laser printer. The monitor can store a large amount of data. If you use
any other type of printer, it can take a long time to print all of the data.

If you attempt to print patient data during the first minute of monitoring, before
the monitor has recorded a snapshot or generated a trend, the monitor might
display the message, "File transfer failure". If this occurs, cancel the AutoPrint
operation and continue monitoring.

Note

Note

Note

Note

The following message might appear when AutoPrint starts:

“To help protect your computer, Windows Firewall has blocked some features of
this program. Do you want to keep blocking this program?”

To prevent this message from appearing again, select Unblock.

AutoPrint works only when the monitor is powered on. This feature helps you be
certain that only the data for the current patient is being printed or, if no patient is
being monitored, that only the data for the last patient monitored is being printed.

If the monitor is off when it is placed in the cradle, AutoPrint is disabled. To enable
AutoPrint, turn the monitor on and select Continue Patient.

If you turn the monitor on and select Start New Patient, all stored patient data is
deleted from the monitor and cannot be printed.

b. Follow the on-screen instructions to install the AutoPrint Utility.

2. Connect the PC to a cradle (Propaq LT Monitor Charging/Communications Cradle),
using the supplied USB cable.

Each time a monitor is inserted into this cradle while the cradle is connected via USB
cable to the PC, the patient data stored in the monitor is printed on the default printer.

Patients monitored continuously for 24 hours typically generate enough data for a 2­or 3-page trends table of two panels per page. For example, a 24-hour report with the
following data (192 rows) would cover three pages:

• 96 rows of vital-signs data (4 intervals/hr = 4 rows per hour) for 24 hours

• 48 NIBP readings (2/hr)

•48 SpO

Figure 98 shows a typical printout.

• Text in italic font indicates one of the trends measurements taken at 15-minute

intervals.

• Text in bold font indicates an NIBP measurement or an SpO

• White text in a black box indicates an alarm condition—a measurement that is
