This textbook teaches the basic concepts of pulmonary physiology to young physicians. Many young pulmonologists, internists, anesthetists, etc., graduate with only a superficial understanding of basic concepts. Given this void, many practitioners miss valuable information available to them in their pulmonary function test results. This book - unlike any other - is organized in the format of a test result report from a pulmonary function laboratory. The first four chapter headings, static function, dynamic function, diffusion and arterial blood gas analysis, are essentially the headings of a standard pulmonary test. Descriptions of physiological principles are intertwined with descriptions of the performance and clinical interpretation of each test. This book serves to enhance our readers' appreciation for information available from pulmonary function testing. This book is an ideal guide for medical students and trainees in pulmonology, but can prove useful to practicing pulmonologists and all medical professionals reading pulmonary function tests.
