User's Manual Part 1

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.
