Primary indications for using positive end-expiratory pressure (PEEP) in conjunction with mechanical ventilation include which of the following?
I.when dynamic hyperinflation occurs in chronic obstructive pulmonary disease (COPD) patients
II.when the imposed work of breathing is excessive
III.when acute lung injury causes refractory hypoxemia

Question

Quizplus · Accepted Answer

PEEP is used in conjunction with mechanical ventilation to improve and maintain gas exchange in patients with refractory hypoxemia, as well as to prevent and reverse dynamic hyperinflation in patients with COPD. The use of PEEP can also reduce the imposed work of breathing, especially in patients with respiratory muscle fatigue. Therefore, options I and III are correct. Option II is also correct.
