Philips M3500B manual Electromagnetic Compatibility, Reducing Electromagnetic Interference

Electromagnetic Compatibility

	Electromagnetic Compatibility
	When using the M3500B defibrillator/monitor (with or without the M3517A
	AC Charger), electromagnetic compatibility with surrounding devices should
	be assessed.
	A medical device can either generate or receive electromagnetic interference.
	Testing for electromagnetic compatibility EMC) of the M3500B with and
	without the appropriate accessories has been performed according to the inter-
	national standard for EMC for medical devices (IEC 60601-1-2). This IEC
	standard has been adopted in Europe as the European Norm (EN 60601-1-2).
	The EMC standards describe tests for both emitted and received interference.
	Emission tests deal with interference generated by the device being tested.
	According to the EMC standards, the M3517A AC Power Module does not
	generate interference.
WARNING	Radio frequency (RF) interference from nearby transmitting devices may degrade
	performance of the HeartStart XLT defibrillator/monitor. Electromagnetic compati-
	bility with surrounding devices should be assessed prior to using the defibrillator.
	Reducing Electromagnetic Interference
	The M3500B defibrillator/monitor and M3517A AC Charger are susceptible
	to interference from other RF energy sources and continuous, repetitive,
	power line bursts. Examples of other sources of RF interference are medical
	devices, cellular products, information technology equipment and radio/tele-
	vision transmission. Should interference be encountered, as demonstrated by
	artifact on the ECG or dramatic variations in SpO2 values, attempt to locate
	the source. Assess:
	Is the interference intermittent or constant?
	Does the interference occur only in certain locations?

Does the interference occur only when in close proximity to certain

￿medical devices?

Does the SpO2 value change dramatically when the M3517A AC Charger is unplugged?
