This companion monograph to West's Respiratory Physiology, which looks at normal respiratory function, focuses instead on the function of the diseased lung. The text offers a concise overview of the disease states of the lung, emphasizing structure and function. For the Sixth Edition, the basic science will be updated to reflect advances in pulmonary pathophysiology in the last five years, including pulmonary function tests, pathophysiology of asthma, pulmonary edema, pulmonary hypertension, air pollution by aerosols, oxygen therapy, and mechanical ventilation. A second interior color is also new to this edition. Intended for second-year medical students taking system-based pathophysiology courses, this book will also prove useful to students in clerkship/rotation.
