Description
Assisted Spontaneous Breathing
Pressure support of insufficient spontaneous breathing.
The function of the machine in assisting insufficient spontaneous breathing is
similar to that of the anaesthetist who manually assists and monitors the
patient's spontaneous breathing by feeling the breathing bag.
The machine takes over part of the inhalation function, with the patient
maintaining control of spontaneous breathing.

The CPAP system supplies the spontaneously
breathing patient with
breathing gas at the slightest inspiratory effort.
Pressure support by ASB is started:
-
when the spontaneous inspiratory flow reaches the set value of the flow
trigger, or at the latest
-
if the spontaneous inspired volume exceeds 25 mL (12 mL in paediatric
mode).
The machine then produces an increase in pressure up to the preselected
ASB pressure-adjustable
to the breathing requirement of the patient.
