PATIENT APNEA Medium No spontaneous cycles were
inititated during Tapnea starting
from the end of the previous
expiratory phase Check for leaks from the mask or tubing.
If necessary, adjust the apnea time.
For the double circuit only, adjust the trigger
value
EXT BATT EMPTY Medium External battery charge less
than 5% Connect the device to mains supply or change
the external battery pack
EXT BATT LOW Low External battery charge less
than 15% Connect the device to mains supply or change
the external battery pack
INT BATT LOW Medium Internal battery charge less than
15% Change the power supply
CIRCUIT OPEN High Patient circuit is poorly
connected Reconnect the patient circuit
Patient circuit is faulty Change the patient circuit
TEST FAILED High Manual test failed Repeat the manual test
MAXI F Low Respiratory rates exceed the
upper threshold of the
Respiratory Rate alarm Check that Respiratory Rate alarm and
inspiratory trigger settings are correct
MAXI LEAKS High Leaks exceed the upper
threshold of the High Leak
alarm Check that the High Leak alarm threshold
setting is correct and check the integrity of
the patient circuit
WRONG CIRCUIT High Type of patient circuit used is
different from the one
determined by the test Check the circuit and repeat the test
LOW PEEP Medium The PEEP delivered to patient is
lower than the target PEEP Check the integrity of the patient circuit
MAXI P EXPI High The expiratory pressure is too
high compared with the target
PEEP Check the expiratory valve control and check
the patient circuit is not blocked
