Atelectasis/collapse. Atelectasis is the collapse of the airspaces which also results in the visual impression of increased soft tissue density. This makes it impossible to distinguish infiltrates from atelectasis on the basis of visual density alone. Considering other factors is therefore required. Atelectasis must have volume loss by definition (collapse of airspaces must reduce lung volume), whereas infiltrate does not. Atelectasis in ICU patients occurs most frequently in the left lower lobe, probably because the heart in the supine position compresses the lower lobe bronchus.
