environment –
guidance
Floors should be wood,
concrete or ceramic tile. If
floors are covered with
synthetic material, the
relative humidity should be
at least 30%.
Mains power quality should
be that of a typical
commercial or hospital
environment.
Mains power quality should
be that of a typical
commercial or hospital
environment.
Mains power quality should
be that of a typical
commercial or hospital
environment.
If the user of the VPAP
requires continued
operation during power
mains interruptions, it is
recommended that the
VPAP be powered from an
uninterruptible power
source
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment
