Question

Question 27 RESPIRATORY FUNCTION: CALCULATION. Not yet answered Marked out of When spirometry is performed by a patient, we compare the observed values to values predicted by studies of the general population. Several factors are put into an equation to generate an ideal or predicted value for FVC, FEV., and FEF25-75. Age, gender, height, and race are important predictors of lung function. Weight is generally not important. The questions which follow compare observed lung function to predicted values. 4.00 Flag question A 35 year old woman presents with a history of progressive shortness of breath on exercise. She denies increased phlegm, but does complain of a dry cough. She is a non-smoker. Her spirometry is as follows: Observed Predicted FVC 2.20 3.67 FEV 1.75 3.02 a) Which type of lung disease does she have (obstructive, restrictive, mixed)? b) What would you predict that her FEF 3.75 would be increased, decreased or normal)? Select one: She has obstructive lung disease (answer to a); therefore the FEF25.75 would also be increased in range answer to b). She has obstructive lung disease (answer to a); therefore her FEF 35-75 would also be normal (answer to b). She has restrictive lung disease (answer to a); therefore the FEF25-75 would also be decreased in range, almost normal (answer to b). Oo oo She has mixed lung disease (answer to a); therefore the FEF25-75 would be normalin range (answer to b). She has mixed lung disease (answer to a); therefore the FEF25-75 would be increased in range (answer to b).

Answer 1

Obstructive lung disease.

FEV will be increased in range.

Because of she denied the increased phlegm

Option a is correct
