Regulatory and Safety Information
Electrode defibrillation recovery is the ability of the electrode to allow the ECG trace
to return after defibrillation. GE Healthcare recommends using non-polarizing
disposable electrodes with defibrillation recovery rating as specified in AAMI
EC12.5.2.2.4. AAMI EC12 requires that the polarization potential of an electrode pair
does not exceed 100 mV 5 seconds after a defibrillation discharge.
Refer to the supplies and accessories guide for this system for a list of approved
electrodes.
Modulating Effects in Digital Systems
This section describes the modulating effects that may occur in digital systems of the
product.
This device uses digital sampling techniques that may produce some variation in
amplitudes of Q, R, and/or S waves from one heart beat to the next, which may be
particularly noticeable in pediatric recordings. If you observe this phenomenon,
be aware that the origin of amplitude variations is not entirely physiological. For
measuring voltages of Q, R, and S waves, GE Healthcare advises using the QRS
complexes with the largest deflection of the particular waves.
Electromagnetic Compatibility (EMC)
Before installing or using the device or system, be aware of the proximity of known
radio frequency (RF) sources, such as:
• Radio and TV stations
• Portable and mobile RF communication devices (cell phones, two-way radios)
• X-ray, CT, or MRI devices
These devices are also possible sources of interference as they may emit higher
levels of electromagnetic radiation.
WARNING:
EQUIPMENT MALFUNCTION OR INTERFERENCE - Use of this equipment adjacent
to or stacked with other equipment should be avoided because it could result
in improper operation. If such use is necessary, this equipment and the other
equipment should be observed to verify that they are operating normally.
WARNING:
EQUIPMENT MALFUNCTION OR INTERFERENCE - Portable RF communications
equipment (including peripherals such as antenna cables and external antennas)
should be used no closer than 30 cm (12 inches) to any part of the ECG device,
including cables specified by the manufacturer. Degradation of the performance
of this equipment could result.
