Comment: Blood gas and pH testing are done to evaluate oxygen and carbon dioxide gas exchange, respiratory function including hypoxia and acid-base status. They are clinically indicated in a wide variety of medical and surgical situations involving cardiorespiratory, metabolic, and central nervous disturbances. Raffin has pointed out that few studies are available to indicated and that a complete list of clinical settings involving ill patients in whom blood gas studies might be indicated would include much of the tables of contents of general medicine texts
