An unknown external battery
pack has been connected
Cause
HP O supply missing

No spontaneous cycles were
inititated during Tapnea starting
from the end of the previous
expiratory phase
External battery charge less
than 5%
External battery charge less
than 15%
Internal battery charge less than
15%
Patient circuit is poorly
connected
Patient circuit is faulty
Manual test failed
Respiratory rates exceed the
upper threshold of the
Respiratory Rate alarm
Leaks exceed the upper
threshold of the High Leak
alarm
Type of patient circuit used is
different from the one
determined by the test
The PEEP delivered to patient is
lower than the target PEEP
The expiratory pressure is too
high compared with the target
PEEP
Solution
Change the power supply
Check that an oxygen supply is connected and

Connect a compatible external battery pack
(Li-Ion type)
Solution
Connect the high-pressure O tube
2
Check for leaks from the mask or tubing.
If necessary, adjust the apnea time.
For the double circuit only, adjust the trigger
value
Connect the device to mains supply or change
the external battery pack
Connect the device to mains supply or change
the external battery pack
Change the power supply
Reconnect the patient circuit
Change the patient circuit
Repeat the manual test
Check that Respiratory Rate alarm and
inspiratory trigger settings are correct
Check that the High Leak alarm threshold
setting is correct and check the integrity of
the patient circuit
Check the circuit and repeat the test
Check the integrity of the patient circuit
Check the expiratory valve control and check
the patient circuit is not blocked
