CPAP/PSV
– Continuous Pressure Ventilation with Pressure
Support
Description::
In this mode, the patient breathes spontaneously on a continuous
positive pressure and breathing is assisted by a Pressure Support
(ΔPS). Usually when analyzing the flow curve, a flow peak is seen
which decreases over time.
Cycling occurs by flow, is adjustable between 5% and 80% peak
inspiratory flow measured.
If the Pressure Support (ΔPS) value is set to 0 (ZERO) or both cycle
trigger ways (pressure or flow) are disabled, pure CPAP mode will be
activated, i.e., without pressure support. In this condition, PEEP
parameter will be displayed as CPAP.
