Reducing Electromagnetic Interference; Restrictions For Use - Philips IntelliVue TRx Instructions For Use Manual

Reducing Electromagnetic Interference

The transceiver and associated accessories can be susceptible to interference
from other RF energy sources and continuous, repetitive, power line bursts.
Examples of other sources of RF interference are other medical electrical
devices, cellular products, information technology equipment, and radio/
television transmission. If interference is encountered, as demonstrated by
artifact on the ECG or dramatic variations in physiological parameter
measurement values, attempt to locate the source. Assess the following:
Once the source is located, attempt to attenuate the interference by distancing
the transceiver from the source as much as possible. If assistance is needed,
contact your local service representative.
Restrictions
Artifact on ECG and other physiological waveforms caused by electromagnetic
for Use
interference should be evaluated by a physician or physician authorized
personnel to determine if it will negatively impact patient diagnosis or treatment.
Draft - 1 Aug 08
• Is the interference due to misplaced or poorly applied electrodes or
sensors? If so, re-apply electrodes and sensors correctly according to
directions in Chapter 6. ECG Monitoring.
• 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 electrical equipment?
