Your answer:The FEV1 had the biggest change.21What lung values changed (from those of the normal patient) in the spirogram when thepatient experiencing an acute asthma attack was selected? Why did these values change asthey 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 emphysemwas 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 ANDFEV1 WHICH TAKE THE BIGGEST HITS.3How 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
Describe the effect that the inhaler medication had on the asthmatic patient. Did allspirogram values return to "normal"? Why do you think some values did not return all theway to normal? 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 layebuild up blocks the airways.5How much of an increase in FEV do you think is required for it to be considered significantlyimproved by the medication?Your answer:10%.61With moderate aerobic exercise, which changed more from normal breathing, the ERV or theIRV? How well did the results compare with your prediction?Your answer:ERV.7Compare the breathing rates during normal breathing, moderate exercise, and heavyexercise.Your answer:they all increased. greatest increase in heavy exercise.8
