Appendix A - Electromagnetic Compatibility
Interference
RF fields pulsating at a sustained rate within the physiological pass band of this equipment may be detected
and then displayed as a valid waveform, or the fields may alter a valid waveform and cause an erroneous
parameter value.
AC line transients may disrupt displayed ECG, RESP and SpO2 waveforms causing noise and erroneous
parameter data; may also affect video display synchronization.
Self recovers when line transients are removed.
Mitigation
Evaluate RF fields on site. Troubleshoot with patient simulators and then determine the source of the
interference. Separate the sensitive receivers from the causes of the interference (refer to the following
table).
Investigate sources of AC line transients in the facility power system; inspect facility ground network;
review equipment operating on the same low voltage circuit; separate suspect sources.
Use a Hospital Grade isolation transformer to protect the monitor from the line transients.
