Patient circuit
leakage
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 located in the patient
circuit. Check for leakage or replace
the patient circuit.
Y Sensor Checks the pressure and flow
measurement of the Y Sensor. Check Y module and Y Sensor. If the
problem persists, change the Y
Module/Sensor.
Pressure transducer Calibrates and checks the
inspiratory and expiratory pressure
transducers. If the Internal leakage test passed (see
above):
• check/replace inspiratory or
expiratory pressure transducer
• check that there is no excess water
in the expiratory cassette
Safety valve 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)
