Dräger Primus User Manual

Pressure support mode (optional)
Pressure-assisted ventilation mode for
patients with spontaneous breathing.
Synchronization and pressure support
for the spontaneous breathing efforts
are controlled via the sensitivity of the
flow trigger and the level of APPS. The
rate at which the pressure curve rises is
pre-set via the rise time TSLOPE.
The maximum inspiratory time for a
spontaneous breathing stroke varies
with age. It is equal to not more than
1.5 seconds in patients under the age of
4 and not more than 4 seconds in
patients with a set age of more than
4 years.
Inspiration is ended as soon as the
actual inspiration flow drops below 25 %
of the inspiratory peak flow. Any leakage
is compensated at the actual airway
pressure at the same time.
Apnoea ventilation can additionally be
set via the minimum frequency FreqMiN.
The ventilator is automaticaily triggered
via Freqmin if there is no spontaneous
breathing activity by the patient. This is
not a mandatory ventilation stroke by the
ventilator; the patient can end the stroke
triggered by the ventilator at any time by
breathing spontaneously. This stroke is
not identified by a trigger indicator.
Apnoea ventilation can also be
deactivated again via FregMIN (OFF
position).
