Curve is based on a change in volume of 13.29 ml and a breathing cycle of 8 s. Emphysema flow rate graph is similar with a change in volume of 18.15 ml and a breathing cycle of 11 s. Solid line is flow rate measured from the spirometer. The dashed line is the two piece polynomial curve fitted to the spirometer data.
