Your answer: The FEV1 had the biggest change. 2 1 What lung values changed (from those of the normal patient) in the spirogram when the patient experiencing an acute asthma attack was selected? Why did these values change as they did? How well did the results compare with your prediction? Your answer: TV, ERV, IRV, RV, FVC, FEV1, and FEV1 (%) values changed when the patient with emphysem was selected. These values changed because the airways are constricted due to muscle spasms and mucus secretions. My prediction ok n was correct because when the lungs are obstructed the fev1 % will be the biggest change because it is a combination of the FVC AND FEV1 WHICH TAKE THE BIGGEST HITS. 3 How is having an acute asthma attack similar to having emphysema? How is it different? Your answer: both are air resistance. emphysema has as problem with the elastic recoil while asthma is muscle spasms. 4

How well did the results compare with your prediction? Your answer: TV, ERV, FEV1% the others didn't return to normal because its a temporary and mucous laye build up blocks the airways. 5 How much of an increase in FEV do you think is required for it to be considered significantly improved by the medication? Your answer: 10%. 6 1 With moderate aerobic exercise, which changed more from normal breathing, the ERV or the IRV? How well did the results compare with your prediction? Your answer: ERV. 7 Compare the breathing rates during normal breathing, moderate exercise, and heavy exercise. Your answer: they all increased. greatest increase in heavy exercise. 8
