What does point A represent on the pressure-time scalar shown in the figure?

A) Plateau pressure
B) Maximum safety pressure
C) Positive end-expiratory pressure
D) Auto-PEEP

Question

What does point A represent on the pressure-time scalar shown in the figure?

A) Plateau pressure 
B) Maximum safety pressure 
C) Positive end-expiratory pressure 
D) Auto-PEEP

Quizplus · Accepted Answer

Auto-PEEP is made visible on a pressure-time scalar with the use of an end-expiratory pause.Point A is not positive end-expiratory pressure because there are areas in the waveform that go down to zero.
