HIGH PRESSURE
•
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.
