Cause/Ventilator Response
Internal battery capacity < 10 min.
or 3%.
(battery voltage < 22.5V)
Consequence: ventilation comes to
a halt.
Abnormally high expired flow during
the inspiratory phase of three
consecutive breaths (in double-limb
setup).
Alarm activation occurs:
After three consecutive breaths.
No FIO sensor detected and the

Battery temperature out of
tolerance.
Consequence: battery charging
stops.

ventilator exceeds the Max FIO
set.
Device internal ambient temperature
out of tolerance range.
The LEAK estimated by the
ventilator exceeds the Max LEAK
alarm threshold.
In V A/C or V SIMV modes, if
•
Inspiratory Pressure is higher than
Max PIP during three consecutive
cycles.
In PSV, CPAP, P A/C, or P SIMV
•
modes, if Inspiratory Pressure is
higher than (P Support or P Control
+ PEEP) + 5 mbar up to 29 mbar or
+ 10 mbar over 30 mbar during
three consecutive cycles.
In PSV or CPAP mode and P Support
•
is set to off, if Inspiratory Pressure is
higher than PEEP + 10 mbar during
three consecutive cycles.
Alarm activation occurs:
After three consecutive breaths.
