3. What lung values changed (from those of the normal patient) in the spirogram when the patient experiencing an acuteasthma attack was selected? Why did these values change as they did? How well did the results compare with yourprediction?4. How is having an acute asthma attack similar to having emphysema? How is it different?5. Describe the effect that the inhaler medication had on the asthmatic patient. Did all spirogram values return to "normal"?Why do you think some values did not return all the way to normal? How well did the results compare with your prediction?6. How much of an increase in FEV1 do you think is required for it to be considered significantly improved by themedication? 7. With moderate aerobic exercise, which changed more from normal breathing, the ERV or the IRV? How well did theresults compare with your prediction?8.
