Alarms
198 Instructions for Use Apollo SW 4.5n
Part Number: 9053586, 3rd edition
The displayed value may differ marginally due to
rounding errors, since Apollo calculates the values
internally with much greater accuracy.
The new alarm limits for P
AW are calculated by the
Apollo on the basis of the mean values for PEAK,
PLAT, and PEEP over the last four machine strokes.
Spontaneous breaths by the patient and triggered
Pressure Support strokes 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.
To restore individual alarm limits for MV and P
AW:
–see “Setting alarm limits” on page 209.
To restore all default alarm limits:
–see “Loading default settings” on page 111.
