Synchronized volume-controlled ventila-
tion with Pressure Support (Optional)
Figure 67. Volume Mode Screen with optional Pressure
Support
Pressure Support is activated during volume-
controlled ventilation by entering a value for the level
of support. This can be defined via the button
>ΔP
PS<.
1. Press the button >ΔP
PS< on the Volume Mode
screen (1 in Figure 67). The key turns yellow,
and the last value set for Pressure Support
appears, together with the last value set for the
trigger sensitivity above it (2 in Figure 67).
The “PressSupp” indication in the status field flashes
on and off (3 in Figure 67).
2. Turn the rotary knob to adjust the Pressure
Support to the desired value, and press the
rotary knob to confirm (4 in Figure 67).
When the value is confirmed, the ”PressSupp”
indication in the status field stops flashing and is
displayed continuously.
If the patient was being ventilated without
synchronization when Pressure Support is activated,
synchronization will now be activated automatically
with the last trigger setting used.
The “sync” indication will appear in the status field
(3 in Figure 67).
Synchronization is maintained with the set value
when Pressure Support is deactivated and set to
“OFF”.
In case of a continuous and strong patient activity, it
is possible that the mandatory breathing effort of the
patient coincides with the pressure supported
ventilation, resulting in an increased tidal volume V
T.
Pressure Support is automatically deactivated when
the trigger is deactivated and set to “OFF”.
The actual trigger sensitivity is shown above the keys
for the ventilation parameters (2 in Figure 67).
