Service Manual PV 501/501-2 INTRODUCTION
1 INTRODUCTION
1.1 The scope of this manual
This manual provides information for the maintenance and service of both the PV 501
and PV 501-2 ventilators. The PV 501-2 is a further development of the PV 501. The
main differences are that the PV 501-2 delivers a maximum patient pressure of 60 mbar
(compared to the PV 501’s 50 mbar) and that theTrigger setting is adjustable between -
-2 to 6 mbar (compared to the PV 501’s -4 to 6 mbar).
The PV 501and PV 501-2 are designed to give many years of trouble-free breathing
assistance to the user provided that preventative maintenance is done at the specified
intervals described in this manual. Correctly performed maintenance will increase the
ventilator's service life considerably.
All points to be checked and service instructions for the PV 501 and the PV 501-2 are
described in this manual. Where information is only relevant to one of the models it is
clearly marked which model the text/figure refers to, otherwise all information is valid for
both models.
It is also important that any peripheral equipment is checked at the same time as the
maintenance service is done.
Also included is a reference copy of the Operation Manual.
1.2 Intended use of the ventilator
PV 501 and the PV 501-2 are volume-controlled, pressure-limited ventilators, specially
designed for long term ventilator assistance at home.
The internal batteries are connected automatically should the mains supply fail or is disconnected. Fully-charged batteries will give a running time of 4 hours.
Thanks to its design, the PV 501 and the PV 501-2 are easy to operate. It does not
require any gas, and together with its low weight, it is ideal for breathing therapy both in
hospital and while travelling.
The PV 501and the PV 501-2 are not intended for intensive care and are aimed for
adults and children weighing about 30 kg or more.
1.3 Design and function of the ventilator
The PV 501and the PV 501-2 are built around a bellows that is compressed and drawn
out by a ball screw driven by an electronically controlled servo motor. The micro-processor controlled electronics calculate the correct speed and running time for the motor by
reading the settings for tidal volume, frequency and the I/E-relationship. The setting limits for pressures and the trigger level are monitored. If the mains supply or the external
battery supply should fail during operation, the internal batteries are automatically connected and an indication of this is given on the front panel. If the battery supply voltage
drops too low, both audible and visual alarms are given. The ventilator's modular design
makes maintenance easy.
1.4 Intended audience
This Service Manual is intended for technicians who have medical/technical training and
knowledge about the construction and function of the ventilator.
It is not intended for clinic personnel or patients.

1.5 Service personnel's training requirements
Thanks to their simple construction using a modular system, no special competence is
required other than general medical technical training on ventilators.
Always contact BREAS MEDICAL if there are any questions or if training is required.
All service must, however, be performed according to the instructions in this manual.

in the figure below. Check that everything seems normal. Create a pressure of
approximately 30 cm H
0 and listen for any leakage.

I/E: 1:2
• Measure the tidal volume and that the volume per minute is cor rect.
(Accuracy ± 10%).
When checking using a volume monitor, an exhalation valve with a peep valve
connector can be required. The volume monitor is then connected to the peep
valve outlet on the exhalation valve.

3.10.3 Calculating the tidal volume/patient pressure
The tidal volume delivered is always slightly less than the tidal volume setting.
This difference is due to the effect of the patient pressure on the compliance of
the bellows.
The diagram below shows these differences at different patient pressures.
Settings: I/E = 1:2, Breath rate = 15 breaths/min. with the patient circuit con-
nected.
Set volume/l itr e s
Fig. 3-2 Volume/Patient pressure diagramme
Example:
A patient needs a tidal volume of 0,7 litres and has an airway pressure of 20 cm
O. Start from 0.7 on the axis for “ Delivered volume”. Draw a horizont al line unti l
H
2
it crosses the line for 20 cm H
O patient pressure. From this point, go straight
2
down and read off the value the tidal vol ume setti ng should be. In this case the
ventilator setting is 0.8 litres.

3.10.4 Checking the pressure limit
Set: Low pressure 10 cmH2O
High pressure 40 cmH
• Check the accuracy (±10%). Check that LED indicati on is given as well as an
audible alarm.
• Also check that the solenoid valve for high pressure "clicks". You can clearly hear
the solenoid valve activate at the following inhalation.

3.10.5 Checking low pressure alarm/alarm mute
• Turn the vent ilator on without anything connected to the patient air outlet. Wait 15
sec until the alarm for "Low pressure" is activated. Press the alarm mute button
and check that the alarm is heard again after approx. 2 min.
3.10.6 Trigger
• Set the trigger knob to -1 c m H20. Create a negative pressure an d check that ther e
is a triggered inhalation. The green LED should light.
3.10.7 Battery operation
• Disconnect the mains cable while the ventilat or is running. Check that the ventilator automatically changes over to internal battery and an alarm is given.
• Reconnect the mains power and check that indication "MAINS" comes on.
3.10.8 Checking accessories Patient circuit
• Inspect the patient circuit and replace it if necessary.
