Setting parameter CPAP PSV
PSV is designed to support insufficient spon-
taneous breathing. It combines the benefits
of pressure-controlled ventilation with the
patient‘s spontaneous breathing activity.
The ventilator uses the selected trigger
threshold to detect the patient‘s inhalation
efforts and then triggers a mandatory breath
using the selected pressure support (Psupp).
With PSV enabled, the ventilator stores the
inspiratory peak flow during inhalation.
Expiration is initiated as soon as the flow has
dropped to the previously set percentage for
the inspiratory peak flow. The Expiration
Trigger Sensitivity (ETS %) is used for this
setting. In pure CPAP ventilation, the Pinsp
setting acts as an parameter for Insp.-Hold.
