11. The operation of each alarm function
should be verified daily.
Periodically check the alarms at
clinically suitable intervals. If the
audible alarm or the visual indicator of
any alarm function fails to activate
during any alarm condition or fails to
reset after the alarm has been cleared,
refer the unit to an authorised service
technician.
12. Before using the ventilator check that
all connections are correct, and verify
that there are no leaks.
Patient circuit disconnects are a hazard
to the patient. Extreme care should be
taken to prevent such occurrences.
It is recommended that Penlon
Safelock fittings are used throughout
the breathing circuit.
Using the Ventilator
13. The AV-S ventilator is not intended for
use in intensive care applications.
14. This apparatus must not be used with,
or in close proximity to, flammable
anaesthetic agents.
There is a possible fire or explosion
hazard.
15. Anaesthesia apparatus must be
connected to an anaesthetic gas
scavenging system (AGSS) to dispose
of waste gas and prevent possible
health hazards to operating room staff.
This requirement must be observed
during test procedures as well as
during use with a patient.
The scavenging transfer and receiver
system must conform to ISO 8835-3.
Any problem arising from an
improperly functioning scavenging
system is solely the user’s
responsibility.
Do not use a scavenging system that
restricts drive gas flow when negative
pressure is exerted on it.
16. When the ventilator is connected to a
patient, it is recommended that a
qualified practitioner is in attendance
at all times to react to an alarm or other
indication of a problem.
17. In compliance with good anaesthesia
practice, an alternative means of
ventilation must be available whenever
the ventilator is in use.
18. It is recommended that the patient
oxygen concentration should be
monitored continuously.
19. If the drive gas supply pressure drops
below a nominal 241 kPa (35 psi), the
LOW DRIVE GAS SUPPLY
alarm will
activate both audibly and visually.
Patient minute volume may be reduced
due to lowered flow rates
20. An audible alarm indicates an
anomalous condition and should never
go unheeded.
21. The characteristics of the breathing
circuit connected between the
ventilator and the patient can modify or
change patient ventilation.
To assist the maintenance of the
delivered patient tidal volume, the
ventilator control system software
includes:
A) a compliance compensation
algorithm,
B) a fresh gas compensation
algorithm.
However, patient ventilation must be
monitored independently from the
ventilator.
It is the responsibility of the user to
monitor patient ventilation.
22. Care must be taken to ensure that the
flow sensors are connected correctly
to the inspiratory and expiratory ports
of the absorber.
23. The Vent Inop (ventilator inoperative)
alarm indicates that one of the
following conditions has occurred:
a) The drive gas solenoid has failed.
b) The flow control valve has failed.
c) Internal electronic fault.
d) Internal electrical fault.
e) Software error.
Note that if a ventilator error is
detected, ‘Ventilator Inoperative’ will be
displayed on the front control panel
display.
