Large arrays of pulmonary physiologic fundamentals are touched on throughout the text. For example, the first case involves a patient with normal physiology in relation to exercise. This leads into discussions of numerous important issues, including descriptions of ventilation; diffusion; oxygen delivery, uptake, and consumption; the oxygen dissociation curve; and finally carbon dioxide liberation. The fact that all these subjects are covered quite effectively in one case is a testament to the value of this book. Another case presents a well-trained mountain climber at high altitude, and subsequently discusses hypoxia, the alveolar gas equation, acid-base physiology, and ventilatory control systems. I particularly enjoyed case three, which deals with COPD. Not only is a good clinical narration given along with the unfortunate but all-too-common outcome, but also a nice pathologic discussion is followed by introductions to pulmonary function testing, pressure-volume curves, ventilation/perfusion mismatch, and pulmonary blood flow. Later chapters include cases on asthma, pulmonary fibrosis, pulmonary embolism, pulmonary edema, pneumoconiosis, and acute respiratory failure.
