Recording ECGs During Defibrillation
NOTICE:
EQUIPMENT DAMAGE — Damaged cables can cause mechanical problems.
Before connecting the cable to the device, check it for signs of physical damage. Do
not use a damaged cable.
For patient safety, use only the original GE Healthcare patient cable.
WARNING:
SHOCK HAZARD — Touching the patient, electrodes, or leadwires during
defibrillation can cause a shock.
During defibrillation, do not touch the patient, the electrodes, or the leadwires.
Observe all defibrillator safety information.
This equipment is protected against the effects of cardiac defibrillator discharge to
allow the ECG trace to return after defibrillation, as required by test standards.
The patient signal input is defibrillation-proof; it is not necessary to remove the ECG
electrodes before defibrillating the patient if non-polarizing electrodes are being used.
When using stainless steel or silver electrodes, the defibrillator discharge current may
cause the electrodes to retain a residual charge, causing an electrode polarization or
DC offset voltage. This blocks ECG signal acquisition for several minutes. If polarizing
electrodes are used, GE Healthcare recommends that you disconnect the leadwires
from the patient before delivering the shock.
To prevent polarization, GE Healthcare recommends the use of non-polarizing
disposable electrodes with defibrillation recover ratings as specified in AAMI EC12
3.2.2.4 (MMS PN 9623-105 Silver MacTrodes, MMS spec TP9623-003), which requires
the polarization potential of an electrode pair not exceed 100 mV five seconds after a
defibrillation discharge.
Generating a Rhythm Report (Manual Recording)
The Resting ECG mode allows you to generate Rhythm Reports, which are printed
reports only. They do not have computer-generated interpretation or measurements,
