General warnings
These statements apply to all aspects of patient monitoring. Statements which apply
specifically to one aspect of monitoring, such as NIBP or SpO2monitoring, are presented
in the corresponding sections of the manual.
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.
WARNING The power cord is the disconnect device to isolate this equipment
from supply mains. Position the equipment so that it is not difficult to reach or
disconnect the cord.
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 52 on page 53.)
WARNING Do not connect more than one patient to a monitor.
WARNING Do not connect more than one monitor to a patient.
WARNING Electric shock hazard. Do not allow the conductive parts of the
patient cable, electrodes, or associated connections of defibrillation-proof applied
parts, including the neutral conductor of the patient cable and electrodes, to
come into contact with other conductive parts, including earth ground. An
electrical short might result, risking electric shock to patients and damage to the
device.
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.
Page 11
Directions for Use Introduction 7
WARNINGWARNING 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
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.” See “Pacer pulse rejection” on page 138 for disclosure of the
pacemaker pulse rejection capability of this instrument.
WARNING Use only accessories approved by Welch Allyn. The use of any other
accessories can result in inaccurate patient data, can damage the equipment, and
can void your product warranty. Refer to the accessory list or
www.welchallyn.com.
WARNING Patient injury risk. Use only accessories approved by Welch Allyn,
including electrodes, lead wires, and patient cables. These approved accessories
are required for electrical protection of the patient during cardiac defibrillation.
WARNING Always use accessories according to the standards of your facility
and according to the manufacturer's directions.
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 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.
WARNING Do not use the pulse oximeter as a replacement or substitute for
ECG-based arrhythmia analysis.
WARNING The bedside patient monitor is the primary alarming source for the
patient.
WARNING The leading cause of patient death or serious injury reported with the
use of patient monitoring equipment is failure to respond to alarms notifying the
user of an adverse change in patient condition. If you are relying on visual alarm
notifications, maintain a clear line of sight and remain within 4 meters of the
monitor. If you are relying on audio alarm notifications, make sure that you can
hear audio alarms from where you are. Set the volume as needed considering the
environment and ambient noise levels. Verify that the alarm is audible to a
clinician working at the maximum distance from the monitor.
WARNING False alarms may occur in some situations. You must understand
and address the cause of the false alarms whenever possible to eliminate the
possibility of repeated false alarms and alarm fatigue, which might result in a
failure to respond to an actual alarm situation.
WARNING Electric shock hazard. Do not allow patient to make contact with
system input ports (input connectors, such as SpO
, ECG, etc.) and system
2
output connectors (output port, such as USB). Additionally, you should not make
contact with the patient and the system input or system output connectors at the
same time.
WARNING Electric shock hazard. All system input and output connectors are
intended for connecting devices that comply with IEC 60601-1 or other IEC
standards (for example, IEC 60950), as appropriate to the device. Connecting
additional devices to the electrocardiograph might increase chassis or patient
leakage currents.
WARNING Defective batteries can damage the monitor. Visually inspect the
battery at least monthly, if the battery shows any signs of damage or cracking, it
must be replaced immediately and only with a battery approved by Welch Allyn.
WARNING Patient injury risk. Keep the monitor, reusable electrodes, and the
patient cable clean. Patient contact with contaminated equipment can spread
infection.
WARNING Patient injury risk. The monitor has not been designed for use with
high-frequency (HF) surgical equipment and does not protect against burns to the
patient.
WARNING Patient injury risk. The data captured from this monitor should not be
used as a sole means for determining a patient’s diagnosis or prescribing
treatment.
WARNING To avoid serious injury or death, take precautions consistent with
good clinical practice during patient defibrillation:
• Avoid contact with the electrocardiograph, patient cable, and patient.
• Place defibrillator paddles properly in relation to electrodes.
Page 13
Directions for Use Introduction 9
WARNING To avoid serious injury or death, take precautions consistent with
good clinical practice during patient defibrillation:
• Before defibrillation, verify that patient leads are properly connected.
• After defibrillation, pull each patient lead out of the patient cable and inspect
the tips for charring (black carbon marks). If there is any charring, the patient
cable and individual leads must be replaced. If there is no charring, fully
reinsert the leads into the patient cable. (Charring can occur only if a lead is
not fully inserted into the patient cable before defibrillation.)
WARNING Patient injury risk. Ensure that each test identifies the patient to
avoid the risk of associating reports with the wrong patients. If any report does
not identify the patient, either write the patient identification information on the
report immediately following the ECG test or enter identifying information before
sending test results.
WARNING To maintain diagnostic accuracy and to comply with IEC60601-02-51
and IEC 60601-02-25, do not scale (resize) when sending a saved ECG to an
external printer.
WARNING Patient injury risk. To prevent cross-contamination and the spread of
infection:
General cautions

WARNING Never download a configuration file to the monitor while you are
monitoring a patient with the monitor in the cradle.
• Changing the monitor configuration shuts down the monitor and deletes all
patient data from the monitor.
Figure 9. Monitor and cradle
The cradle is intended to hold the monitor when the patient is in bed or is otherwise
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
Monitor
Cradle
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 91.)
• Uploading the configuration file from the monitor to the PC.
Page 22
18 Overview of monitor operation Welch Allyn Propaq LT Vital Signs Monitor
• Uploading patient data from the monitor to the PC for printing. (See “Printing
patient data” on page 111.)
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.
2. Connect the AC adapter to an AC power outlet and to the cradle. The indicator
(green) on the front of the cradle indicates that the AC power adapter is connected.
Figure 10. Cradle status indicators
Green Monitor battery charging
Yellow Battery or charger failed
(Indicates either that the temperature of
the battery pack is out of range or that
service is required.)
Green AC power connected
3. Insert the monitor into the cradle. When the monitor is properly seated, it clicks into
place. (green) on the cradle indicates that the monitor battery is charging. (See
“Recharging the battery” on page 133.)
Note
The monitor can be inserted into the cradle when power is on or off. If monitor
power is on, inserting the monitor in the cradle or removing the monitor from the
cradle does not interrupt patient monitoring.

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.

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 31. Wearable strap
1. Place the wearable strap on the sitting or standing patient and adjust all components
for a comfortable, secure fit (Figure 31 left).
2. Connect the wearable strap securely to the monitor strap mounts (Figure 31 right).
3. Carefully arrange the strap and the monitor on the patient to avoid bruising or other
skin injuries.

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.

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.
Info
Demo
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, aVR,aVL,oraVF). You can also display the SpO2or
Resp waveform in place of an ECG waveform.
Page 52
48 Standalone monitoring Welch Allyn Propaq LT Vital Signs Monitor
WARNING Always monitor and set alarms for SpO2when 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.
WARNING Make sure the patient mode is correct. Incorrect patient mode can
result in inaccurate heart rate readings and inappropriate alarm settings.
WARNING Electric shock hazard. Do not allow the conductive parts of the
patient cable, electrodes, or associated connections of defibrillation-proof applied
parts, including the neutral conductor of the patient cable and electrodes, to
come into contact with other conductive parts, including earth ground. An
electrical short might result, risking electric shock to patients and damage to the
device.
Page 53
Directions for Use Standalone monitoring 49
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 Always use the provided garment clips to route ECG cables away
from the patient’s head.
WARNING Use only accessories approved by Welch Allyn. The use of any other
accessories can result in inaccurate patient data, can damage the equipment, and
can void your product warranty. Refer to the accessory list or
www.welchallyn.com.
WARNING Always use accessories according to the standards of your facility
and according to the manufacturer's directions.
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
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.

WARNING For safe and effective use of electrodes, follow the electrode
manufacturer’s directions.
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.

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 52 on page 53.)
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 31.)
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 138.), 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 31.)
2. Highlight ECG.
Verify that the setting for Power source filter is correct for the power source in your

Monitoring SpO
The monitor can be purchased with the Nellcor or the Masimo SpO2option. Most of this
chapter pertains to either configuration. Monitors with the Masimo technology, however,
can provide additional SpO2data. (“About the Masimo SpO2display” on page 60.)
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
www.welchallyn.com. Inspect sensors and cables, and discard any that are
damaged. Do not use a sensor with exposed optical components.
WARNING If you need to increase the length of the sensor cable, use only one
extension. Use of multiple extensions can adversely affect performance. Do not
attach any cable that is intended for computer use to the SpO2connector at the
monitor.
WARNING Tissue damage and erroneous measurements can be caused by
incorrect application or use of a sensor. (Examples of bad practices: wrapping the
sensor too tightly, applying supplemental tape, failing to periodically inspect the
sensor site, leaving a sensor on too long in one place.) Refer to the
manufacturer’s directions for specific instructions on application and use, and for
description, warnings, cautions, and specifications.

accessories listed in the accessory list or at
2
WARNING Do not modify the sensor.
WARNING Do not wet the sensor or immerse it in fluid. Do not attempt to
sterilize a sensor.
WARNING Sensors exposed to ambient light while not applied to a patient can
exhibit seminormal saturation readings. Be sure the sensor is securely placed on
the patient and check its application often to ensure accurate readings.
WARNING Inaccurate measurements might be caused by venous pulsations.
WARNING The pulse oximeter can be used during defibrillation, but the
readings might be inaccurate for a short time.
WARNING Do not use the pulse oximeter as an apnea monitor.
WARNING During SpO2monitoring, a very sudden and substantial change in
pulse rate can result in erroneous pulse rate readings. Always validate the patient
data and patient condition before effecting an intervention or a change in patient
care.
Page 61
Directions for Use Standalone monitoring 57
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 SpO2readings.
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.
WARNING Functional testers cannot be used to assess the accuracy of a pulse
oximeter monitor.
Caution If liquid gets into the SpO2connector cavity, discontinue SpO
2
monitoring until the liquid is removed and the cavity is dry.
Note
This monitor does not normalize the SpO2waveform.
1. Inspect the SpO2cable. Replace it if it shows any signs of wear, breakage, or fraying.
2. Plug the cable into the sensor and the monitor.
Each SpO2sensor is intended for application to a specific site and site size on the
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 SpO2sensor to the patient according to the manufacturer’s directions for
use, observing all warnings and cautions.
5. Confirm that the monitor displays SpO2data within thirty seconds of being 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 SpO2alarms when NIBP and SpO2are monitored
simultaneously, place the NIBP cuff and the SpO2sensor on different limbs.
• Do not attach the SpO2sensor on the same limb as an arterial catheter or
intravascular line.
• The pulse signal can disappear if any of the following conditions exists:
- the sensor is too tight
Page 62
58 Standalone monitoring Welch Allyn Propaq LT Vital Signs Monitor
- 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
hypothermia
• If poor perfusion affects performance for an adult, consider using the adult nasal
sensor.
• If a sensor is connected and the sensor light does not come on within 3 seconds:
- Verify that SpO
is turned on (Figure 56 on page 58)
2
- Replace the sensor
• If excessive or prolonged patient movement interferes with measurements,
consider the following possible solutions:
- be sure the sensor is secure and properly applied
- use a new sensor with fresh adhesive backing
- select a different type of sensor
- move the sensor to a less active site
6. Periodically verify that the sensor remains properly positioned on the patient.

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 142 for values.)
WARNING The decision to use the device on pregnant or pre-eclamptic patients
is at the discretion of the trained clinician using the equipment.
WARNING Do not apply the NIBP cuff over a wound.
WARNING Patient injury risk. Inaccurate measurement risk. Do not place the
cuff where it can disturb proper circulation. Do not place the cuff on any area
where circulation is compromised or on any extremity used for intravenous
infusions.
WARNING Patient injury risk. Do not place the cuff on the arm on the same side
of a mastectomy. If necessary, use the femoral artery in the thigh to take a
measurement.
Caution Pulse-rate measurements generated through the blood pressure cuff
or through SpO2are subject to artifact and might not be as accurate as heart-rate
measurements generated through ECG or through manual palpation.
Caution Do not allow the blood pressure cuff hose to be restricted by
compression.
When the monitor is powered on, the default cuff inflation pressure is based on the
patient mode. (See “Default inflation pressure” on page 142.) After an NIBP
measurement occurs, the monitor adjusts the inflation pressure to optimize subsequent
NIBP measurements.
Page 67
Directions for Use Standalone monitoring 63
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 a technical alarm.
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
accessory list or at www.welchallyn.com.
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 61. 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 SpO2, you can reduce or
eliminate unnecessary SpO2alarms by placing the cuff and the SpO2sensor on
different limbs.
5. Screw the hose connector onto the NIBP air connector on the top of the monitor (see
Figure 4 on page 11).
6. Press to start a reading.
Within a few seconds, the pump starts, the cuff begins to inflate, and the manometer
screen appears.

• 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
Page 69
Directions for Use Standalone monitoring 65
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 65.)
• Verify that the ECG leads are properly connected to the patient, and monitor ECG
during NIBP. (ECG monitoring is required for Smartcuf.)
Note
The message ???/???/(???) in an NIBP TREND display or printout indicates that
the monitor could not complete an NIBP measurement during that period.
Note
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
Smartcuf can function only when ECG is being monitored.
To enable Smartcuf
1. Simultaneously monitor ECG and NIBP.
2. Access the Setup menu. (See “To access the setup menus” on page 31.)
3. Highlight NIBP, highlight Smartcuf, and enable the Smartcuf filter.
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.
Page 70

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 62.)
2. Highlight NIBP and press .
3. Highlight NIBP Mode and select Auto.
4. Highlight Auto Interval (min) and select an interval.
Note
To stop automatic NIBP readings
1. Highlight NIBP and press .
2. Highlight NIBP Mode and select Manual.
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.
Taking NIBP readings using Turbo mode
WARNING Patient injury risk. Bruising of the patient’s limb can result from the
NIBP cuff when the device is used in 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 62.)
2. Highlight NIBP and press .

Overview
Physiological and technical alarms
A Physiological (high-priority) 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.
A Technical alarm warns of an equipment condition, such as a low battery or a detached
lead. When a technical alarm 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 technical alarm tone sounds.
WARNING Patient injury risk. Do not set the alarm parameters to extreme
levels. Setting extreme parameters could render the alarm system useless,
causing the potential for patient injury.

2. Check the patient and provide appropriate care.
3. 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 91), 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,or60 minutes.
Note
Note
The factory default suspension period is 4 minutes.
• If it is configured to Disabled, you cannot suspend the alarm tone at the monitor.
• If it is configured to Always On and you set Suspend Audible Alarms to On,
then the alarm tone remains suspended until:
• you set Suspend Audible Alarms to Off or
• monitor power is turned off and then turned on again or
• the monitor is reconfigured
Suspend Audible Alarms does not affect the behavior of the alarm reset
feature ( ). Pressing always either silences a sounding alarm tone for 90
seconds or resets the audible alarm if it was already silenced.
To suspend the alarm tone
1. Access the Setup menu. (See “To access the setup menus” on page 31.)
2. Highlight Suspend Audible Alarms).

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.
Note
To temporarily change alarm limits for the current patient
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.
5. Repeat from step 3 for other alarm limits you want to change for the same vital sign.
6. Press .
When the monitor is turned off, you will have a choice of saving the current settings and
stored patient data or deleting the current settings and patient data. Neither choice affects
the default settings for the monitor.
The default alarm limits are set by your facility. Contact your facility administrator
for more information.
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 127.
Responding to a high-priority alarm
A high-priority alarm condition is indicated on the monitor in the following ways:
• The RED indicator (rightmost of three) above the display screen flashes.
• The alarm banner is displayed in the status panel.
• 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.
Page 82
78 Physiological and technical alarms Welch Allyn Propaq LT Vital Signs Monitor
Responding to a medium-priority alarm
A medium-priority alarm condition (“Overview” on page 71) is indicated on the monitor in
the following ways:
• A flashing yellow light above the monitor display.
• A yellow message on the monitor display (for example, NO ECG CABLE DETECTED).
• Repeated sounding of the medium-priority alarm tone sequence (if tones are not
suspended): 3 long tones and a pause. For a low-priority alarm, a single beep occurs.
Figure 70. Example medium-priority screen
The yellow light flashes during an alarm
and while the alarm is silenced.
To respond at the monitor to a technical alarm
1. Press to silence the tone for 90 seconds; press to clear the alarm.
2. Troubleshoot and correct the problem. (See “Technical alarm messages and status
messages” on page 80.)

Overview
Monitor configuration
The monitor can be configured in various ways.
Each facility can define as many default configurations as required to both meet the
needs of individual departments and units and to conform to the facility’s general
methods and standards.
• Each time the patient mode is changed, the monitor settings return to the default
configuration settings for that patient mode.
• Each time the monitor is turned on, the clinician chooses either to retain the most
recently used temporary, patient-specific settings or to reset the monitor to its
default configuration.
Clinicians can use the monitor buttons to customize settings to meet the needs of
individual patients. These custom settings can be
• discarded when the monitor is turned off and then restarted.
• retained when the monitor is turned off and then restarted.
• saved as the new default configuration for the monitor.
Note
If you change alarm limits while monitoring a patient, you can make these
changes either temporary or permanent. See “Changing alarm limits” on
page 77.
About factory configuration
When the monitor arrives from the factory, it is fully configured and ready for operation.
The factory configuration defines every setting and behavior for the monitor. Each
setting and behavior defined in the factory configuration remains in effect until it is
changed by a custom configuration or by a temporary adjustment. Unless the factory
configuration is replaced by a custom configuration, the factory settings and behaviors are
restored to the monitor each time the monitor is powered up and Start New Patient is
selected.
When a custom configuration is downloaded to the monitor, the settings and behaviors
defined in the custom configuration become the power-up defaults for the monitor, and
the factory configuration is no longer in effect. However, the factory configuration
information can always be restored by qualified service personnel and can also be
restored by downloading the configuration file PropaqLTFactoryConfig.mnt from a PC to
the monitor.
The factory settings are shown in the “Parameter configuration matrix” on page 92.

About default configuration
Most facilities, before putting a new monitor into service, reconfigure it to conform to
local protocol and to adapt it to the clinical environment in which it is to be used. This
reconfiguration results in a set of default settings and monitor behaviors.
Creating a custom default configuration requires the following:
• A Propaq LT Monitor Configuration Utility running on a PC, and
• A cradle with the USB data transfer option
For information about the monitor Configuration Utility, refer to “Using the Configuration
Utility to configure the monitor” on page 104.
To learn which parameters can be defined using the Configuration Utility, see the
“Parameter configuration matrix” on page 92.
About temporary configuration
While monitoring a patient, you can use the monitor buttons to temporarily adjust many of
the monitor settings to accommodate the needs of a specific patient. These custom
settings persist through a power cycle if you select to save patient data on shut-down.
They persist until they are changed manually, or until the monitor is powered down and
then powered up to monitor another patient.
Note
To learn which parameters can be temporarily defined using the user interface, see the
“Parameter configuration matrix” on page 92.
If you change alarm limits while monitoring a patient, you can make these
changes either temporary or permanent. For complete information, see
“Changing alarm limits” on page 77.
Parameter configuration matrix
This table lists the factory settings and the possible values for all parameters, and
indicates which parameters and settings can be defined by the Configuration Utility, or by
the clinician through the monitor buttons.
