Compressive atelectasis

Last revised by Daniel J Bell on 30 Jul 2020

Compressive atelectasis refers to a form of lung atelectasis due to compression by a space-occupying process.

Some authors describe it as a subtype of passive (relaxation) atelectasis where the reduction in lung volume is greater than its normal relaxed state 1. Whereas others describe it as the intrapulmonary counterpart of passive (relaxation) atelectasis due to an intrapulmonary mass lesion 4.
