Since World War II there has rapidly developed a scheme of pulmonary-function tests which quantitatively analyze the patient's ability to breathe. This development is analagous to that of liver-function tests and kidney-function tests.
"The Lung: Clinical Physiology and Pulmonary Function Tests," by Dr. Julius Comroe and co-workers, at the University of Pennsylvania, presents the system of analysis of the patient with breathing difficulties which has been in use in 1955, gives the reason behind individual procedures, and shows clinical situations in which the tests are helpful. The recent uses of alveolar ventilation, ventilation-blood flow ratios, blood-gas diffusion, and compliance studies are handled, as well as older ideas about lung volumes and blood gas analysis. Physicians who have been appalled by the complicated mathematical presentation of pulmonary physiology in review papers will be pleased with the frequent use of understandable diagrams. Ten case studies illustrate application of the tests. An appendix
