Filter and smoothing techniques
• Target volume that can be set:
In the "slow" level, the device checks after every
8 breaths if the target volume has been reached and
changes the pressure by 0.5 hPa. If the pressure
reaches a corridor around the target volume, the
device switches to exact regulation.
In the "medium" level, the device checks after every
5 breaths if the target volume has been reached and
changes the pressure by 1.0 hPa. If the pressure
reaches a corridor around the target volume, the
device switches to exact regulation.
In the "fast" level, the device checks after every breath
if the target volume has been reached and changes the
pressure by 1.5 hPa. If the pressure reaches a corridor
around the target volume, the device switches to exact
regulation.
•Alarms:
The "low minute volume" and "low tidal volume"
alarms are triggered if at least three of the last five
breaths were below the alarm limit. The alarms are
reset automatically as soon as the corresponding
alarm limit is exceeded again with at least three of the
five breaths.
If a target volume is activated, the "low tidal volume"
alarm is only triggered once IPAPmax or PDIFFmax has
also been attained.
The "Apnea" alarm is triggered if apnea is identified
which is longer than the set alarm limit. The alarm is
reset automatically as soon as the end of the apnea is
identified.
