Spirometry is the most commonly used test of pulmonary function. It is a measurement of the amount (volume) and/or speed (flow) of air that can be exhaled. Traditionally, the result of this test is represented graphically as a plot of the volume of air exhaled against time during a forced expiratory manoeuvre: the forced expiratory spirogram (Fig. 3.2).
