Abstract
Atelectasis is derived from the Greek words ateles and ektasis meaning “incomplete expansion or stretching” [1]. The terms “atelectasis,” “collapse,” and “loss of lung volume” are used synonymously implying reduced inflation of the lung. In broad sense, atelectasis denotes diminished air within the lung associated with volume decrease, and generally, it manifests as increased density. Atelectasis can be differentiated by its volume decrease from consolidation in which volume is maintained because air is replaced by liquid or cells of approximately equal volume (Figs. 11.1, 11.2, 11.3, 11.4, 11.5, 11.6, and 11.7).
