Introduction
If other electrodes are used, disconnect the patient cable from the system before
delivering the defibrillation shock.
NOTE:
If excessive DC voltages are present at the electrode, then a message is displayed
indicating a Lead Off condition.
ADS (cubic spline correction) can cause a signal delay of approximately 2 seconds;
therefore they should be disabled if the patient has to be defibrillated while the ECG
is being recorded.
Accuracy of the Input Signal Reproduction
• Overall System Error is tested using the method described in AAMI EC11 3.2.7.1.
Overall System Error is less than +/-5%.
• Frequency Response is tested using the method described in AAMI EC11 3.2.7.2
methods A and D.
Modulating Effects in Digital Systems
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 this phenomenon is observed,
the clinician should be aware that the origin of amplitude variations is not entirely
physiologic. For measuring voltages of Q, R, and S waves, it is advisable to use the QRS
complexes with the largest deflection of the particular waves.
Modem Requirements
Modems supplied by GE Healthcare are designed to comply with applicable country
requirements (such as USA FCC 47CFR68, CE EU R&TTE 1999/5/EC). Refer to the
device for a registration number and ringer equivalence number (REN). The modem
is designed for use on standard device telephone lines. Connection to telephone
company-provided coin service (central office implemented systems) is prohibited.
Connection to party lines service is subject to state tariffs.
An analog telephone line is required. A digital PBX line does not work. If you have any
questions about your telephone line, such as how many pieces of equipment you can
connect to it, the telephone company provides this information upon request.
The registration number and ringer equivalence number (REN) are listed on the
equipment label. To assure proper service from your telephone company, connect no
more than five RENs per telephone line. In some cases, you may not be able to use
five RENs on a given line.
If any of your telephone equipment is not operating properly, you should immediately
remove it from your telephone line, as it may cause harm to the telephone network. If
the telephone company notes a problem, they may temporarily discontinue service.
When practical, they notify you in advance of this disconnection. If advance notice
is not feasible, you are notified as soon as possible. When you are notified, you are
given the opportunity to correct the problem and you are informed of your right to file
a complaint.
