Small atelectasis
Webb23 dec. 2004 · Pulmonary atelectasis may be caused by a variety of factors, which have been classified into three basic mechanisms. Compression atelectasis occurs when the transmural pressure distending the alveolus is reduced. Absorption atelectasis occurs when less gas enters the alveolus than is removed by uptake by the blood. WebbAbsorption atelectasis refers to a loss of lung volume caused by the resorption of air within the alveoli, the small air sacs of the lungs. Atelectasis is a common complication of …
