Instructions for use Primus Infinity Empowered SW 4.5n 115
Operation
Apnea ventilation can additionally be set by means
of the minimum frequency FreqMIN (C). The venti-
lator is automatically triggered by Freq
MIN 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 spontane-
ously. This stroke is not identified by a trigger indi-
cator.
Apnea ventilation can also be deactivated again by
means of Freq
MIN (OFF position).
Continuous Positive Airway Pressure
CPAP – in Pressure Support Mode
(optional)
Spontaneous breathing at an increased pressure
level to increase the functional residual capacity.
Continuous Positive Airway Pressure is activated in
Press. Support when the value for pressure sup-
port
∆
PPS is set to ≤2 [hPa (cmH2O)].
At the same time, the minimum frequency Freq
MIN
is set to OFF and the rise time TSLOPE is set to 0.0.
Apnea ventilation with minimum frequency is not
appicable in the CPAP mode.

to yield a maximum ratio of 1:1 for I:E, thus ensuring an
adequate expiratory time.
