The monitor is safe for patients and clinicians when used in accordance with the
instructions and with the warning and caution statements presented in this manual.
All personnel must read and understand all warning and caution statements
presented in this manual before using the monitor.
• Failure to understand and observe any warning statement in this manual could
lead to patient injury, illness, or death.
• Failure to understand and observe any caution statement in this manual could
lead to equipment damage or loss of patient data.
Directions for Use Introduction 5
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 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 63 on page 57.)
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.
6 Introduction Welch Allyn Propaq LT Vital Signs Monitor
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
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 145 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 Always use accessories according to the standards of your facility
and according to the manufacturer's directions.
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.
Directions for Use Introduction 7
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.
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 and a central station is a backup alarm source. The central station is only
as reliable as its network and should be relied on only as a backup alarming
device.
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 or the central station. 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
or central station.
General cautions
WARNING Auto-reboots occur and wireless connection is occasionally
disrupted. During this period, the bedside monitors continue to provide their
primary alarming functions. Auto-reboots occur infrequently, due to poor
environmental conditions. Failure to perform preventative maintenance can
increase the frequency of occurrence.
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.
Caution Do not autoclave the monitor.
Caution Autoclave accessories only if the manufacturer's instructions clearly
direct you to do so. Many accessories can be damaged by autoclaving.
Caution Changes or modifications not expressly approved by Welch Allyn could
void the purchaser’s authority to operate the equipment.
Caution This product contains no user-serviceable components. Any
unauthorized changes to the product invalidate Welch Allyn’s warranty and also
invalidate all applicable regulatory certifications and approvals.

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

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.

If you select French, HR/PR alarm limits cannot be turned off unless you go
through the service menus to change this setting. If you do change this setting,
the change stays in effect through power cycles.
For information about using the service menus, refer to the Propaq LT Monitor
Service Manual (810-1811-XX).
The monitor always powers on in this language until the setting is changed again. The
setting can be changed again only if one of the following occurs:
• This procedure is repeated.
• A new configuration is downloaded from a PC. (See “Using the Configuration
Utility to configure the monitor” on page 116).
• 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 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
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 103.)
• 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 97.)
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 129.
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 37.)
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 103.
To lock out the configured elements
Hold down , , and simultaneously for 5 seconds.

Using the Large Color Display Interface (‘interface box’) optional accessory, you can
display patient vital signs from the monitor on a full-size screen. It receives video signals
from the cradle via a VGA cable.
WARNING All signal input and output (I/O) connectors are intended for
connection of only devices complying with IEC 60601-1, or other IEC standards
(for example, IEC 60950), as applicable to the monitor. Connecting additional
devices to the monitor may increase chassis or patient leakage currents. To
maintain operator and patient safety, consider the requirements of IEC 60601-1-1.
Measure the leakage currents to confirm that no electric shock hazard exists.
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
Caution If you require medical-grade protection against leakage current, install
an approved power conditioner between the large color display power cable and
the mains power.
The various configurations are not interchangeable. Each requires a unique
combination of screws, USB and power cables, and VGA cable.

To change between 4-waveform and 9-waveform views, insert a wire into the small hole
in the interface box near the USB connector, or press the button.
If you change the display format at least 15 seconds before shutting off power to the
interface box, the newly selected display becomes the default display when the interface
box is next powered on.

and aVF are available in the 9-waveform view.
Installing the interface box
The Large Color Display Interface receives DC power from the AC power adapter and
vital-signs data from the cradle. It provides DC power to the cradle and the video signal to
the large display.

When the interface box is attached to the cradle, the default power and USB cables
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 are used.
The AC power adapter 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.
