Operation
If the pressure is not to be increased any further
during the maneuver, touch the Descend now
button (O) and confirm. The pressure will then be
reduced again in steps. The duration of the
maneuver is reduced as a result.
To cancel the maneuver, touch the Cancel
button (P) and confirm. If required, the PEEP can
be adjusted before confirming. This can be useful,
e.g., when the desired effect has already been
achieved during the maneuver. The ventilation will
now continue immediately with the previous
settings and the adjusted PEEP.
Due to the technically related delay between the
set and the measured airway pressures, it may
happen that the current and the last measured
pressures differ by up to one step level.
The cursor can be used to display the previous
measured values. To do this, touch screen
area (K) and move the cursor with the rotary knob.
To facilitate reading the data, screen area (K) will
temporarily not be updated. To show the current
measured values again, touch area (L).
