For both types of exercise the tidal volumes and

For both types of exercise, the tidal volumes and breathing rates were increased. Compared with normal values, did tidal
volume or breathing rate increase more during moderate exercise? (Determine the percentage by which each value
changed.)

1. What lung values changed (from those of the normal patient) in the spirogram when the patient with emphysema was
selected? Why did these values change as they did? How well did the results compare with your prediction?
