General information
Intended use
The Micropaq™ monitor is intended to be used by clinicians for single or multiparameter
vital signs monitoring of ambulatory and nonambulatory pediatric and adult patients in
health care facilities. The monitor is able to withstand light rain exposure over short
periods of time (uniform distribution of approximately 1 mm of water/ minute for 10
minutes or less).
The Micropaq monitor is intended to operate with an Acuity® Central Monitoring System
through wireless communication over Welch Allyn’s FlexNet™ network. FlexNet connects
multiple devices to the Acuity Central Monitoring System through hardwired Ethernet
networks and Wireless Local Area Networks (WLANs). If the Micropaq monitor is moved
out of range or loses communication with the FlexNet network, it continues to monitor
the patient, display patient data, and generate local patient alarms or alert messages.
• The ECG channel is intended primarily for five-lead ECG monitoring, although
three-lead ECG monitoring is supported.
• The Pulse Oximetry channel is intended for continuous noninvasive monitoring of
functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate
(measured by an SpO2 sensor).
The most likely locations for patients monitored by this device are step-down units,
telemetry departments, general medical/surgical floors, emergency departments, and in-
hospital transport.
This guide was written for clinicians. Although this guide may describe some monitoring
techniques, Welch Allyn expects that the operator is a trained clinician who knows how to
take and interpret a patient’s vital signs.
Federal USA law restricts sale of the device identified in this manual to, or on the order of,
a licensed medical practitioner.

minimum 6-inch distance between the monitor and pacemaker. Immediately
turn the monitor off and provide appropriate patient care if you have any reason
to suspect that the monitor is interfering with the pacemaker. The Health
Industry Manufacturers Association recommends this minimum 6-inch distance
between a hand-held wireless radio and a pacemaker, which is consistent with
the independent research by, and recommendations of, Wireless Technology
Research.
WARNING Make frequent electrical and visual checks on cables, sensors, and
electrode wires. All cables, sensors, and electrode wires must be inspected and
properly maintained and in proper working order to allow the equipment to
function properly and protect patient safety.
WARNING Avoid electrosurgery burns at monitoring sites by ensuring proper
connection of the electrosurgery return circuit so that the return paths cannot be
made through monitoring electrodes and probes.
WARNING Use of ECG and SpO2 cables not specified by Welch Allyn may
negate defibrillator protection and risk patient injury.
WARNING Use of Masimo LNOP® sensors/cables will not provide protection
in accordance with IEC defibrillation standards when used with this device.
WARNING To ensure patient safety, the conductive parts of the ECG
electrodes (including associated connectors) and other patient-applied parts
should not contact other conductive parts, including earth ground, at any time.
WARNING Motion artifact can affect the accuracy of patient vital sign
measurements. Minimize patient motion whenever possible.
WARNING Use only accessories supplied by Welch Allyn or recommended in
the Welch Allyn Products and Accessories booklet (810-0409-XX). The monitor
will only meet the listed specifications when using accessories listed by Welch
Allyn. Use accessories according to your facility’s standards and the

8Chapter 1 General information Welch Allyn Micropaq Monitor
Understanding the monitor and the FlexNet Network
The monitor is intended to operate with an Acuity® Central Station as part of Welch Allyn’s
FlexNet network. FlexNet allows multiple devices to communicate through hardwired
Ethernet networks and Wireless Local Area Networks (WLANs). The Acuity Central
Station provides the primary display and entry of patient data for a patient connected to
the monitor.
Each patient-worn monitor supports two-way communication with an Acuity Central
Station through an access point in the FlexNet network. The access point is a digital radio
transceiver that connects to the FlexNet network. During monitoring, the monitor sends
the patient data to Acuity. Acuity and the monitor continuously analyze the data. Acuity
provides appropriate alarm or alert messages at the Central Station and other network
devices such as a hallway message panel and the monitor itself. Acuity also stores the
patient data for viewing or report printing.
If the monitor is moved out of range or loses communication with the FlexNet network
and Acuity, it continues to monitor the patient and display patient data. While not
communicating with Acuity, the monitor continues to generate local patient alarms or
alert messages. Patient data is not stored and Acuity does not perform waveform analysis
or generate arrhythmia messages while the monitor is not communicating with Acuity.
When the monitor is returned to within range of the FlexNet network, it automatically
reconnects to Acuity.

WARNING Motion artifact can cause incorrect heart rate readings. Minimize
patient motion whenever possible.
WARNING If a disconnected lead is in too close proximity to other electrical
devices, it may cause false heart rate readings.
WARNING The monitor does not provide internal arrhythmia analysis.
Therefore, arrhythmias may cause the monitor to display inaccurate heart rates.
WARNING The monitor will show + + + for HR numerics between 301 and
350 beats per minute. Above 350 beats per minute, it may display incorrectly
low heart rates, due to intermittent picking of R-waves.
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 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 “ECG specifications” on page 51 for disclosure of the
pacemaker pulse rejection capability of this instrument.
22 Chapter 2 Monitoring Welch Allyn Micropaq Monitor
• Even though the monitor contains fully isolated patient-connected circuitry, it has not
been specially designed for direct application on a patient’s heart.
• Use only with accessories provided or recommended in the Welch Allyn Products and
Accessories booklet (810-0409-XX).
• Severe artifact and interference (such as defibrillation interference) can cause the
waveform to move off the display for a few seconds before it is restored.
WARNING For patients with a pacemaker, position the monitor to maintain a
minimum 6-inch distance between the monitor and pacemaker. Immediately
turn the monitor off and provide appropriate patient care if you have any reason
to suspect that the monitor is interfering with the pacemaker. The Health
Industry Manufacturers Association recommends this minimum 6-inch distance
between a hand-held wireless radio and a pacemaker, which is consistent with
the independent research by, and recommendations of, Wireless Technology
Research.
WARNING 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. Reading errors and
damage to equipment may also result. This hazard can be reduced by (1)
avoiding the use of small ECG electrodes, (2) selecting ECG electrode
attachment points remote from the surgical site and from the electrosurgical
return electrode, (3) using electrosurgical return electrodes with the largest
practical contact area, and (4) assuring proper application of the electrosurgical
return electrode to the patient.
WARNING Verify patient mode at Acuity. Incorrect patient mode may result in
inaccurate heart rates and inappropriate alarm settings.
WARNING To help prevent injury, use the provided garment clips to route the
ECG cables away from the patient’s head.
WARNING Use of ECG cables with loose or faulty detachable lead wires may
cause erratic behavior of the ECG waveform due to intermittent ECG lead wire
connections.
WARNING To ensure patient safety, the conductive parts of the ECG
electrodes (including associated connectors) and other patient-applied parts
should not contact other conductive parts, including earth ground, at any time.
Caution To protect the monitor from damage during defibrillation, 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.
Caution Do not use an ECG cable longer than 10 feet (3 meters). If the nominal
length of the ECG cable, including extensions, exceeds this length, the monitor
is not guaranteed to meet published electromagnetic compatibility (EMC)
performance specifications.
Directions for Use Chapter 2 Monitoring 23
Perform 5-Lead ECG monitoring
1. Inspect the ECG cable and replace it if it shows any signs of wear, breakage, or
fraying. Plug the cable into the monitor.
2. Select electrode sites on the patient.
Choose flat areas; avoid fatty or bony areas and major muscles.
3. Shave or clip hair from electrode sites, thoroughly clean skin, and lightly rub dry.
You may use soap and water, isopropyl alcohol or special skin preparation pads. To
avoid allergic reactions to electrodes, refer to the electrode manufacturer’s directions.
4. If you are using pre-gelled electrodes, make sure the electrode date is not expired and
the gel is intact and not dried out. For best results, use only silver/silver chloride
electrodes.
If you are using ungelled electrodes, apply a 1/4- to 1/2-inch mound of gel over the
electrode contact area.
For best product performance and measurement accuracy, do not use stainless steel
needle electrodes, squeeze bulb electrodes, or electrodes with dissimilar metals. Due
to polarization, such electrodes can generate offsets beyond the monitor’s
capabilities. Do not use electrodes from more than one manufacturer on the same
patient.
5. Attach lead wires to the electrodes before applying them to the patient. Apply the
electrodes to the patient in the proper locations.
If the monitor detects that some lead wires are not properly connected, the monitor
displays a chest diagram and indicates which leads are disconnected.
The locations of the circles displayed on the monitor for each lead are fixed, and are
not affected by the exact placement of the electrodes on the patient. For example,
the C lead can be placed on the patient in any one of the V1-V6 locations desired, but
will only be displayed on the monitor in the location shown above.
Flashing circle indicates the
lead is not connected.

waveform, heart rate, and other patient data.
To change the ECG lead selection, press to display the Main Menu. Then press
Scroll Down to highlight ECG LEAD . . . , then highlight ECG 1 or ECG 2 and press
to change the lead.
3-Lead ECG application with the 5-Lead ECG cable
You can perform 3-lead ECG monitoring in a similar manner as 5-lead ECG monitoring. You
may use the 5-lead ECG cable with detachable electrode lead wires, and connect only the
lead wires and electrodes for RA, LA, and LL. Refer to the Welch Allyn Product and
Accessories booklet (810-0409-XX) for part numbers.
Follow these steps:
1. Pe r f o r m Step 1 through Step 4 on page 23 as described for 5-lead ECG monitoring.
2. Before attaching electrodes to the patient, attach only lead wires for RA, LA, and LL to
the 5-lead ECG trunk cable and to the electrodes. Make sure that lead wires for C and
RL are DETACHED from the 5-lead ECG trunk cable.
3. Apply the electrodes for RA, LA, and LL to the patient in the proper locations.
The monitor displays the chest diagram with two circles blinking confirming that the C
and RL electrodes are not connected.
4. Observe the monitor and visually confirm that within about 30 seconds, the two
circles disappear and the monitor displays the ECG waveform, heart rate, and other
patient data.
Be aware that if you connect the C or RL lead wires to the 5-lead ECG trunk cable and
apply the C or RL electrodes to the patient, the monitor defaults to 5-lead ECG
monitoring and does not enable 3-lead ECG monitoring. To enable 3-lead ECG
monitoring, you must disconnect the ECG cable from the monitor for a few seconds,
and then begin this procedure again.
Note
Be aware that there are some inherent limitations with this application,
especially when compared to 5-lead ECG monitoring. These limitations include
the restriction to only one displayed lead, ECG lead II. Because only one
displayed lead is available (ECG lead II), factors such as a poor electrode
connection at RA, LA, or LL can significantly affect performance. To overcome
these limitations, the 5-lead ECG monitoring is preferred.
The monitor’s 3-lead ECG monitoring is only available for use with Acuity
software versions 6.1 or later.
Directions for Use Chapter 2 Monitoring 25
Be aware that only ECG lead II is available for display with the monitor’s 3-lead ECG
monitoring. No other ECG lead selections are available.
3-Lead ECG application with the 3-Lead ECG cable
Refer to the Welch Allyn Product and Accessories booklet (810-0409-XX) for part numbers.
Follow these steps:
1. Pe r f o r m Step 1 through Step 4 on page 23 as described for 5-lead ECG monitoring.
2. Attach lead wires to the electrodes before applying them to a patient.
3. Apply the electrodes for RA, LA, and LL to the patient at the proper locations. If the
monitor detects one of the lead wires is not properly connected, it will display a chest
diagram indicating which lead is disconnected.
4. Observe the monitor and visually confirm it displays the ECG waveform, heart rate,
and other patient data.
Be aware that only ECG lead II is available for display with the monitor’s 3-lead
monitoring. No other ECG lead selections are available. The monitor will not detect
the presence of a 3-lead cable until two or more of its leads are connected to the
patient.
3-Lead ECG application with the 3-Lead ECG cable and cable extension
This combination functions the same way as the 3-lead ECG application with the 5-lead
cable. For electromagnetic compatibility (EMC) reasons, do not use an ECG cable and
extension cable length of more than approximately 10 feet total.
WARNING Do not try to perform this 3-lead ECG monitoring with any 5-lead
ECG cable that does not have detachable electrode lead wires as described
above. Attempting to perform this procedure with a 5-lead ECG cable which has
lead wires cut off or hanging loose and not connected to the patient would
present a shock hazard to the patient or clinician.
Note
Be aware there are some inherent limitations with this application, especially
when compared to 5-lead ECG monitoring. These limitations include the
restriction to only one displayed lead, ECG II lead. Because only one displayed
lead is available (ECG lead II), factors such as poor electrode connection at RA,
LA, or LL can significantly affect performance. To overcome these limitations,
the 5-lead ECG monitoring is preferred.
The monitor’s 3-lead ECG monitoring is only available for use with Acuity
software versions 6.1 or later.
26 Chapter 2 Monitoring Welch Allyn Micropaq Monitor
Perform SpO2 monitoring
WARNING Oxygen saturation measurements using pulse oximetry are highly
dependent on proper placement of the sensor and patient conditions. Patient
conditions such as shivering and smoke inhalation may result in erroneous
oxygen saturation readings. If pulse oximetry measurements are suspect, verify
the reading using another clinically accepted measurement method, such as
arterial blood gas measurements on a co-oximeter.
WARNING Use only accessories as listed in the Welch Allyn Products and
Accessories booklet (810-0409-XX). Use only Masimo accessories and sensors
with the Masimo SpO2 option. Use only Nellcor accessories and sensors with
the Nellcor SpO2 option. The monitor will only meet the listed specifications
when using accessories listed by Welch Allyn.
WARNING Use of Masimo LNOP® sensors/cables will not provide protection
in accordance with IEC defibrillation standards when used with this device.
WARNING Tissue damage can be caused by incorrect application or use of a
sensor (e.g., 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 Directions for Use provided with each sensor for specific
instructions on application and use, and for description, warnings, cautions, and
specifications.
WARNING Sensors exposed to ambient light while not applied to a patient can
exhibit semi-normal saturation readings. Be sure the sensor is securely placed
on the patient and check its application often to ensure accurate readings.
WARNING Inaccurate measurements may be caused by venous pulsations.
WARNING The pulse oximeter can be used during defibrillation, but the
readings may be inaccurate for a short time.
WARNING The pulse oximeter should NOT be used as an apnea monitor.
WARNING A very sudden and substantial change in pulse rate can result in
erroneous pulse rate readings. Be sure to validate the patient data and patient
condition before intervention or change in patient care.
WARNING Interfering Substances: Carboxyhemoglobin may erroneously
increase readings; the level of increase is approximately equal to the amount of
carboxyhemoglobin present. Methemoglobin may also cause erroneous
readings. Dyes, or any substances containing dyes, that change usual arterial
pigmentation may cause erroneous readings.
Directions for Use Chapter 2 Monitoring 27
1. Attach the SpO2 sensor to the patient according to the manufacturer’s directions for
use, observing all warnings and cautions.
Each SpO2 sensor is designed for application to a specific site on the patient within a
certain size range. To obtain optimal performance, use an appropriate sensor and
apply it as described in the sensor’s directions for use.
If excessive ambient light is present, cover the sensor site with opaque material to
block the light. Failure to do so may result in inaccurate measurements. Light sources
that can affect performance include surgical lights (especially those with a xenon light
source), bilirubin lamps, fluorescent lights, infrared heating lamps, and direct sunlight.
If NIBP will be monitored while using SpO2, place the NIBP cuff on a different limb
than the SpO2 sensor to help reduce unnecessary SpO2 alarms. For optimal
measurements, avoid placing the SpO2 sensor on the same limb as an arterial
catheter or intravascular line.
Loss of pulse signal can occur if the sensor is too tight, there is excessive ambient
light, an NIBP cuff is inflated on the same limb as the sensor, there is arterial
occlusion proximal to the sensor, the patient is in cardiac arrest or shock, or the
patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia.
2. Inspect the SpO2 cable. Replace it if it shows any signs of wear, breakage, or fraying.
Plug the cable into the sensor and the monitor.
3. After the cable is connected, confirm that the monitor displays SpO2 data within a
few seconds.
4. If excessive 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
The SpO2 system is designed to work satisfactorily during normal patient motion.

Monitor a patient out of range of Acuity
While out of range of Acuity, the monitor continues to monitor the patient and provide
local HR/PR and SpO2 alarms or alerts at the monitor as needed.
When the patient wearing the monitor goes out of range of Acuity, do the following:
1. A DROPOUT equipment alert occurs at the Acuity Central Station. Acknowledge the
alert at Acuity.
2. An equipment alert occurs at the monitor with this message:
ACUITY CONNECTION LOST
Depending on how the monitor is configured (as controlled by Acuity), this alert can
also cause the monitor to emit audible alert tones.
If tones are enabled, the authorized person should press on the monitor to
acknowledge (dismiss) the alert and silence this instance of the alert tone.
When the patient returns within range of Acuity, the monitor automatically reconnects to
