Interpretation and evaluation of pulmonary function tests

Abstract

Evaluation of pulmonary function is essential for the diagnosis and management of respiratory disease and other conditions. Various tests are available. Some, such as spirometry and pulse oximetry, are widely used in a variety of healthcare settings; others, such as those that measure diffusing capacity and static lung volumes, are performed in specialist pulmonary function laboratories. This article examines some of the pulmonary function tests available.
