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%.
AC power ("mains") quality
should be that of a typical
commercial or hospital
environment.
AC power ("mains") power
quality should be that of a
typical commercial or hospital
environment.
AC power ("mains") power
quality should be that of a
typical commercial or hospital
environment. If the user of the
ventilator requires continued
operation during power mains
interruptions, it is
recommended that the
ventilator be powered from an
uninterruptible power supply or
a battery.
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical commercial
or hospital environment.
