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.
