Question

Based on the chart, I need help answering these 2 questions!

1. Based on the subject above, Did the analysis of lung volumes indicate any restrictive or obstructive defect at rest? Did the subject meet any of the ACSM clinical recommendations to warrant a pulmonary function test?

2. How did FVC, FEV1/FVC and FEV1 change after exercise? Based on these changes, does the subject appear to have any exercise induced asthma?

Answer 1

1) It is very important to know the ratio of FEV1/FVC to identify any obstructive or restrictive disorders .

It is shown in image :

It is very important to know the ratio of FEV1/FVC to identify any obstructive or restrictive disorders . It is shown in image: FEV_1/FV_e = n = 80% spirometry obstructive disorders eg: Bronchial asthma FEV_1/FVC Material implication low implication is normal but explanation is obstructed therefore V_C is normal while FEV , decreases. restrictive disorders eg: Emphysema spondylitis FEV_1/FVC = normal or high chest expansion is restricted. Both FEV_1 & FVC decreases. FEV_1 may be normal: so , FEV_1/FVC will be normal or high In your case , FEV ,/FVC is 80% patient is normal not having any type of respiratory disorder. Patient is still not having any respiratory disorder . So it doesn't require any of the ACSM clinical recommendation. 2) effect of exercise is shown as: Effect of exercise: - FEV_1 rightarrow increases FVC rightarrow Decreases FEV_1/FVC rightarrow Increases Inyour case , values FEV_1 , FVC , FEV_1/FVC changes according to above 2 - min post exercise These values return to normal values after sometime. Patient is can't said to be exercise - induced asthma .

Patient is still not having any respiratory disorder . So it doesn't require any of the ACSM clinical recommendation.

2) effect of exercise is shown as :
