Pulmonary Function Testing & Interpretation is a comprehensive guide to lung function tests, such as spirometry, lung volume and diffusing capacity. Beginning with an introduction to the history of respiratory physiology, structure and function, and preparation for testing, individual chapters explain different types of test and the interpretation of result based on gender, age and body size. Written by a leading USA-based expert, the book introduces new ways to interpret spirometry values, as well as assess the effectiveness of aerosol-based bronchodilator drugs on obstructive airway disease.
