Question

During a pre-operative evaluation, bedside spirometry results are as follows: FVC 88% of predicted, FEV1 85% of predicted, FEV1/FVC 82% of predicted and FEF25-75 81% of predicted. How should the respiratory therapist interpret these results?

A. a mild restrictive disorder
B. a mild obstructive disorder
C. normal lung function
D. mixed obstructive/restrictive disorder

Answer 1

The respiratory therapist should interpret these results as a normal lung function.

Step-by-step explanation:

The respiratory therapist should interpret these results as a normal lung function. In this case, the FVC is 88% of predicted, which is within the normal range. The FEV1 is 85% of predicted, also within the normal range. The FEV1/FVC ratio is 82% of predicted, indicating normal lung function. Finally, the FEF25-75 is 81% of predicted, which is again within the normal range.

These results suggest that there are no significant abnormalities or restrictions in lung function. The patient is able to exhale a normal amount of air within a specific time frame, indicating that there is no obstructive lung disease. Additionally, there are no limitations in the ability to inhale or exhale due to a restrictive lung disorder.
