Operation
Ventilation mode Pressure Support
(optional)
Pressure Support (Pressure Support) is a
pressure-supported ventilation mode for patients
with spontaneous breathing. Patients who make
no inspiratory effort must not be ventilated with
Pressure Support.
The ventilation mode Pressure Support is
triggered by the inspiratory effort of the patient.
Most anesthetic agents cause a reduced reaction
of the patient to carbon dioxide and hypoxemia.
Therefore ventilation modes, which are triggered
by patients, do not ensure adequate ventilation in
these conditions. In addition, the use of muscle
relaxants negatively influences the triggering by
the patient.
In Pressure Support ventilation mode, the apnea
ventilation function is available, which can ensure
a minimum ventilation. To activate apnea
ventilation, for the setting Freq Min another setting
must be selected than OFF. If the detected
spontaneous respiratory rate of the patient drops
under the set value for Freq Min, a mechanical
breath is applied. Apnea ventilation is not intended
to be a primary ventilation mode.
For apnea ventilation, Fabius uses the settings for
the following parameters:
– ∆PPS
– Freq Min
– Insp Flow
– PEEP
If 2 successive mechanical breaths occur with
apnea ventilation, the alarm message APNOEA
VENTILATION !! is displayed in the alarm
message field. The alarm message is deleted as
soon as a spontaneous breath is detected.
Changing to Pressure Support mode
In the following examples and illustrations, the
change from Volume Control mode to Pressure
Support mode is described:
1 Press the Pressure Support (A) key.
2 Adjust ventilation settings (B).
3 Confirm the new mode.
