Abstract

The objective of this chapter is to introduce the displaceable lung volumes. Simple spirometry is a basic tool for the evaluation of airway function and is commonly the first test performed when a chronic respiratory disease is suspected. By measuring dynamic volumes and flows during forced expiratory and inspiratory maneuvers, it provides a valuable contribute in identifying respiratory diseases associated with some ventilatory defects. It can be used for diagnosing and monitoring respiratory disease, for preoperative risk stratification, and as a tool in epidemiologic and other research studies. The interpretation of spirometry requires the comparison of the parameters measured in the patient with those obtained by adequate reference equations. A bronchial reversibility test is always indicated when spirometry reveals airway obstruction.
