The correct answer to this question is C, 20 cmH20. PEEP stands for positive end-expiratory pressure. This is the pressure in the lungs, which would be above atmospheric pressure and it would appear at the end of expiration. There are two types of PEEPs.

The first is an extrinsic PEEP, which is one applied by a ventilator The second is an intrinsic PEEP, which is caused by incomplete exhalation. This occurs when one is trying to take the next breath. Once identified, the pressure build-up must be reduced or stopped altogether. Both PEEPs can lead to a drop in blood pressure or an increase in intrathoric pressure.
