Pacemaker - GE Marquette Responder 3000 Operator's Manual

6 Pacemaker

Some Basic Facts
Application and Functional Description
The transcutaneous pacemaker of the Marquette
Responder® 3000 is used for external (transchest)
cardiac stimulation in emergencies. It is applied
temporarily in cases of acute arrhythmia, such as
cardiac arrest or Stokes-Adams attacks. Specific
forms of bradycardia and tachycardia can also be
treated with the pacemaker.
The pacemaker offers two modes of operation:
demand and fixed-rate pacing ("Fix").
The pacer pulses are delivered via the adhesive
defibrillation electrodes (pace pads). Electrodes
919 202 94 (for adults) and 919 202 09 (for
children) can be used.
Separate ECG electrodes must be applied for
acquisition of the ECG signal.
Warning
Shock Hazard — Due to their functional require-
ments, pacemakers operate with high voltages and
are therefore equipped with specially protected
outputs. Nevertheless, it is important not to touch
live contacts with conductive metal objects, such
as tweezers, as long as the pacemaker is operating.
Currents exceeding 10 µA may induce ventricular
fibrillation, if they flow through the heart.
Observe the following sequence of operating steps
when turning the pacemaker on and off:

Pacemaker
Turning the pacemaker ON:
1. Apply ECG electrodes to patient.
2. Connect ECG electrodes to the device.
3. Turn on the Marquette Responder® 3000
(energy selector to
4. Check ECG and vital signs.
5. Attach pace pads to patient.
6. Connect pace pads to the Marquette
Responder® 3000.
7. Turn the pacemaker ON (button
Turning the pacemaker OFF:
1. Turn the pacemaker OFF (button
2. Disconnect pace pads from the Marquette
Responder® 3000.
3. Remove pace pads from patient.
4. If monitoring of the patient is no longer
required, turn off the Marquette Responder®
3000 (energy selector to OFF).
5. Remove ECG electrodes from patient.
Success of the Intervention — Verify the success
of pacemaker stimulation by measuring the pulse
rate, not the heart rate.
Pausing the Pacemaker — Pushing the
button automatically pauses the pacer output and
suspends delivery of pacer pulses. Pressing the
Start
button will terminate the pacer pause and
Pause
resumes pacing with the previous settings.
