Patient circuit leakage
test Checks the patient circuit leakage,
with patient tubing connected, using
the inspiratory and expiratory
pressure transducers. Allowed
leakage: 80 ml/min at 50 cmH
2
O.
Will allow the system to calculate a
compensation for circuit compliance
(if the leakage requirements are
met).
If the internal leakage test has
passed, the leakage is to be located
to the patient circuit. Check for
leakage or replace the patient
circuit.
Y Sensor test Checks the pressure and flow
measurement of the Y Sensor. Check Y module and Y Sensor. If
problem persists, change Y sensor.
If problem still presists, change Y
module
Pressure transducer test Calibrates and checks the
inspiratory and expiratory pressure
transducers. If the Internal leakage test passed
(see above):
Check/replace Insp. or Exp.
pressure transducer.
Check that there is no excess water
in the expiratory cassette. Refer to
pages 202 and 203.
Safety valve test Checks and if necessary adjusts the
opening pressure for the safety valve
to 117 ± 3 cm H
2
O.
Check the inspiratory section:
Check that the safety valve
membrane is correctly seated in the
inspiratory pipe.
Check that the inspiratory pipe is
correctly mounted in inspiratory
section.
Check that the safety valve closes
properly when the Pre-use check is
started (distinct clicking sound from
the valve).
