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 2 sensor detected and the
FIO 2 alarm is active.
Battery temperature out of
tolerance.
Consequence: battery charging
stops.
The level of oxygen delivered by the
ventilator exceeds the Max FIO 2 level
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.
or
• 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.
or
• 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.
Consequence:
• Switch to exhalation phase.
