                                     Intended use of the Ventilator
The PV 401 is a pressure-controlled, pressure-monitored
ventilator, especially developed for treatment in the home
of patients with chronic breathing difficulties.
The PV 401 is designed to give many years of trouble-free
breathing assistance to the user provided that preventive
maintenance is done at the specified intervals described in
this manual.
Well-performed maintenance will increase the service life of
the Ventilator considerably. It is also important that any
peripheral equipment and accessories are checked at the time
the service is carried out.

 Design and function of the Ventilator
The PV 401 is constructed around a bellows and a drive screw
assembly driven by an electronically-controlled servo-motor.
A microprocessor controls the correct speed of the motor and
its power supply by means of calculations based on the
settings for pressure, rate, inspiration time etc. The set
pressure and the trigger level are monitored at the same time.
In the event of a mains power supply fail, the Ventilator
will automatically switch to the external battery supply.
This is indicated by the LED in the On/Off button
flashing. If the external battery voltage drops too low, an
audible alarm is given.
