This video explains how spirometry is used to measure various aspects of lung function, including tidal volume, inspiratory reserve, expiratory reserve, residual volume, and vital capacity. It also discusses how this test can be used to diagnose restrictive and obstructive lung diseases.

• 00:00:00 Spirometry is a test used to measure lung function and to diagnose lung diseases. The test consists of breathing into a spirometer and recording the air volumes and breathing speed. Volumes are measured in tidal, inspiratory reserve, expiratory reserve, residual, and vital capacity. Obstructive lung diseases, such as asthma or COPD, show a decreased total lung capacity, while restrictive lung diseases, such as inspiratory restrictive disease, have normal vital capacity. Vital capacity can be measured with forced vital capacity, which is reduced when breathing rapidly.
