Adapting limits – AutoSet
When the ventilation settings have been made, Julian
can automatically adapt the alarm limits for the minute
volume (MV) and airway pressure (PAW) to the
current ventilation settings in CMV mode.
Press the softkey »auto set limits«. The alarm limits
menu opens automatically.
The alarm limits for MV and PAW are adapted.
At the same time, an advisory message is displayed:
"MV and PAW limits have been automatically
adapted". The menu closes again automatically after
5 seconds.
The new alarm limits for the set MV are calculated by
Julian as follows:
Upper alarm limit
MV Measured MV · 1,4
[L/min] At least 2,0
Julian calculates the new PAW alarm limits by
determining PEAK, P
Plateau
methods and selecting the higher value as the
"measured value".
Method 1:
The mean of the last 4 measured breaths. If fewer
measured values are available, these are used as the
basis of determination.
Method 2:
The measured value of the last breath.
Julian sets the upper alarm limit for PAW to the absolute
higher determined measured value of
– PEAK + 5 mbar or
– P + 10 mbar, but at not less than 10 mbar
Plateau
in CMV/PCV.
Julian sets the lower alarm limit for PAW from the
determined measured values to
– PEEP + 0,6 · (P – PEEP),
Plateau
and not less than 4 mbar in CMV/PCV.
To reset individual alarm limits for MV and PAW:
See "Displaying and setting alarm limits"
on page 70.
To reuse all default alarm limits:
See "Configuring in standby mode,
setting default alarm limits" on page 98.
