Which of the following statements about the equal pressure point (EPP) is true?

Question

Quizplus · Accepted Answer

At some point along the airway, the pressure inside equals the pressure outside in the pleural space. This point is referred to as the EPP. Downstream from this point, pleural pressure exceeds the airway pressure. The resulting positive transmural pressure gradient causes airway compression and can lead to actual collapse. Airway compression increases expiratory airway resistance and limits flow. At the EPP, greater expiratory effort only increases pleural pressure, further restricting flow. In airways of healthy subjects, the EPP occurs only with forced exhalation and at low lung volumes.
