Electromagnetic Immunity: Non Life-Supporting Functions

Non life-supporting functions of the Propaq MD include : 12-lead ECG, EtCO
SpMet, NIBP, IBP, Temp, Impedance Respiration
Guidance and manufacturer's declaration – electromagnetic immunity – for non–
life supporting equipment and systems
The non life-supporting functions of the Propaq MD are intended for use in the electromagnetic environment
specified below. The customer or user of the Propaq MD should ensure that it is used in such an environment.

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.
a. 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 Propaq MD is used exceeds the applicable RF
compliance level above, the Propaq MD should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Propaq MD.
b. Over the frequency ranges 150 kHz to 80 MHz field strength should be less than 3 V/m.

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

where is the maximum output power rating
of the transmitter in watts according to the
transmitter manufacturer and d is the
recommended separation distance in meters.
Field strengths from fixed RF transmitters, as
determined by electromagnetic site survey,
should be less than the compliance level in
each frequency range.
Interference may occur in the vicinity of
