What is the optimal breathing pattern for intermittent positive-pressure breathing (IPPB) treatment of atelectasis?

Question

Quizplus · Accepted Answer

Slow, deep breaths held at end-inspiration are the optimal breathing pattern for IPPB treatment of atelectasis. This allows for greater lung expansion and maximum recruitment of alveoli. Rapid or shallow breaths may not provide enough pressure to effectively open collapsed alveoli. Holding the breath at end-inspiration allows for more time for alveoli to remain open and exchange gas.
