EID for Life-Support Functions
Guidance and manufacturer’s declaration – electromagnetic immunity – for life-supporting equipment and systems.
The life-support functions a of the M Series are intended for use in the electromagnetic environment specified below.
The customer or user of the M Series should ensure that it is used in such an environment.
a. The life-support functions on the M Series are defined to be any function associated with ECG monitoring, pacing, defibrillation, and shock
analysis. Specifically, these functions include, but are not limited to, the ECG waveform monitoring from leads or pads, the pacing pulse
output, QRS detection, defibrillation energy discharge, and shock advisory functions.

Electromagnetic environment – guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the M Series,
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.

b. The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567
MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.

Interference may occur in the vicinity of equipment
marked with the following symbol:
c. The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz are
intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into
patient areas. For this reason, an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in
these frequency ranges.
d. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment
due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the
M Series is used exceeds the applicable RF compliance level above, the M Series should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the M Series.
e. Over the frequency ranges 150 kHz to 80 MHz field strength should be less than 10 V/m.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
