Introduction
Pulmonary function tests provide measures of Airflow, Lung Volumes, and Flow-Volume Loop , Basic pulmonary function tests available in the ambulatory setting include Spirometry Pulse oximetry Spirometry and Pulse Oximetry provide physiologic measures of pulmonary function and can be used to quickly narrow a differential diagnosis and suggest a subsequent strategy of additional testing or therapy. More complicated testing includes Measurement of lung volumes Lung, chest wall, and respiratory system compliance Complete Exercise Testing None These tests provide a more detailed description of physiologic abnormalities and the likely underlying pathology. The choice and sequence of testing are guided by information taken from the Evaluation of the Pulmonary Patient .
