Dräger Evita 4 - Cpap, Cpap;Asb

CPAP, CPAP/ASB
Continuous Positive Airway Pressure
Assisted Spontaneous Breathing
Spontaneous breathing at a raised pressure level in order
to increase the functional residual capacity (FRC).
Spontaneous breathing can be assisted with additional
pressure by ASB.
For patients breathing spontaneously.
Set the pattern of ventilation for CPAP and CPAP/ASB
with the following ventilation parameters:
O2 concentration »O2«
Positive end-expiratory pressure »PEEP«
Pressure support »PASB«
Pressure rise time » «
––––––––––––––––––––––––––––––––––––––––––––––––
To set:
● Touch the appropriate screen knob.
● Adjust to the desired value = turn rotary knob.
● Confirm setting = press the rotary knob.

CPAP and CPAP/ASB can be expanded with the
following ventilation parameters:
Flowtrigger – for synchronisation with attempted
spontaneous breathing by the patient.
By setting the trigger level, the mandatory ventilation
strokes are synchronised with the patient's spontaneous
breathing attempts.
Spontaneous breathing activity by the patient is indicated
by the brief display of a lung symbol instead of the usual
symbol for the patient mode.
Apnoea Ventilation – for automatic switch-over to
volume-controlled mandatory ventilation if the patient
stops breathing.
If breathing stops, Evita 4 emits an alarm after the set
alarm time (TApnoea > ) and starts volume-controlled
ventilation with the set ventilation parameters.
