Question

_______ the pressure in the lungs (alveolar pressure) above atmospheric pressure (the pressure outside of the body) that exists at the end of expiration. 1 point positive end expiratory pressure barometric pressure systolic pressure diastolic pressure am i right? submit answer

Explanation:

To solve this, we analyze each option:

• "positive end expiratory pressure" (PEEP) is defined as the alveolar pressure above atmospheric pressure at the end of expiration, matching the description.
• "barometric pressure" is atmospheric pressure, not related to alveolar - atmospheric pressure difference at end - expiration.
• "systolic pressure" is the blood pressure during heart contraction, irrelevant here.
• "diastolic pressure" is blood pressure during heart relaxation, also irrelevant.

Answer:

A. positive end expiratory pressure
