Pressure Support Breaths
For Pressure Support breaths 10 , flow is delivered to elevate the circuit pressure to the Pressure
Support setting and maintain it at that pressure until the flow drops below a variable percentage of the
peak flow. Pressure Support breaths may also be cycled by a variable time limit, or by exceeding 2
breath periods. Pressure support breaths are patient type breaths.
For some patients, it may be useful to adjust the variable flow termination percentage. Adjusting the
FLOW TERM setting between 10% and 40% will change the length, volume and comfort of the
inspiration.
10 Pressure Control and Pressure Support breaths do compensate for PEEP. For example, a Pressure Control
setting of 20cmH 2 O and a PEEP setting of 10cmH 2 O results in a Peak Inspiratory Pressure (PIP) of 30cmH 2 O
(20 cmH 2 0 over the set PEEP).
