Treatment settings vary widely, from intensive care or postsurgical care units and extended care/subacute reha- bilitation facilities to outpatient pulmonary centers and the home setting. REVIEW OF RESPIRATORY STRUCTURE AND FUNCTION Respiration is a general term used to describe gas exchange within the body and can be categorized as either external respiration or internal respiration. Basic terms are described here but an in-depth discussion of respiratory physiology, including diffusion and perfusion, goes well beyond the FIGURE 25.1 Anterior view of the rib cage.
