PSV

Pressure Support Ventilation
Pressure-supported ventilation synchronised with the patient's
own breathing. The patient determines the duration of the
inspiration and the ventilation frequency.
The ventilation stroke is terminated when the inspiratory flow
drops to about 15 % of the peak flow or, at the latest, after T
This mode is intended for spontaneously breathing patients
with sufficient regulation of their breathing who are to be
supported with an adjustable inspiratory pressure. Particularly
suitable for weaning the patient from ventilation.
If the patient suffers apnoea, ventilation is executed at the
frequency determined by T
I
Press the keys »Vent. Mode«, »PSV« and »On«.
Combining PSV with:
– separate expiratory flow VIVE: see page 49.
– volume guarantee VG: see page 46.
Adjust the rotary knobs »P
»Insp. Flow « to obtain the desired ventilation pattern.
Ventilate only with a plateau!
The actual inspiration time and the tidal volume are displayed.
Adjust »T « for the maximum permissible inspiration time.
I
Adjust the frequency of the background ventilation
with »T «.
E
Adjusting the trigger volume: see page 37.
If self-triggering occurs, increase the trigger volume.
Setting the alarm limits: see page 50.
Use PSV only at a leakage rate of up to about 40 %.
If the yellow LED blinks, consider:
– The inspiratory time in PSV is set too short and the PSV
breath is ended.
– The tidal volume delivered is less than the VG tidal volume
set. The »VT low« alarm is generated.
