Adapting alarm limits
When ventilation settings have been made, Primus
Infinity Empowered can automatically adapt the
alarm limits for minute volume MV and the airway
pressure P
AW to the current parameters in Volume
Mode, Volume AF, Pressure Mode, and Pressure
Support (optional).
z Press the auto-set limits soft key (A). The
alarm limits menu opens automatically.
The alarm limits for MV and P
AW are adapted and
highlighted by dark green background (B).
To quit the alarm limits menu:
z Push the rotary knob or the key.
The new alarm limits for MV are calculated by
Primus Infinity Empowered from the measured
value for the minute volume MV in Volume Mode,
Volume AF, Pressure Mode, and Pressure Sup-
port (optional).
The displayed value may differ marginally due to
rounding errors, since Primus Infinity Empowered
calculates the values internally with much greater
accuracy.
The new alarm limits for PAW are calculated by
Primus Infinity Empowered on the basis of the
mean values for PEAK, PLAT, and PEEP over the
last four mechanical breaths. Spontaneous breaths
by the patient and triggered pressure support
breaths are not taken into account.
If the mean of the last (up to four) measured
breaths cannot be calculated, the measured value
of the last breath is used instead.
