Recommended separation distances between portable and mobile RF communications
equipment and the A

6000A emergency ventilator
The A
Ⅱ
6000A emergency ventilator is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the A
Ⅱ
6000A
emergency ventilator can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
A

For transmitters rated at a maximum output power not listed above the recommended
separation distance d in metres (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
NOTE 1 An additional factor of 10/3 is used in calculating the recommended separation
distance for transmitters in the ISM frequency bands between 150 kHz and 80 MHz and in the
frequency range 80 MHz to 2,5 GHz to decrease the likelihood that mobile/portable
communications equipment could cause interference if it is inadvertently brought into patient
areas.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
