A patient’s pulmonary function results are:
%of predicted
- SVC 61
- FVC 63
- FEV1 83
- FEV1/FVC% 81
- DLCO 26
What is most likely this patient’s condition?
- Chronic Bronchitis
- Asthma
- The patient doesn’t have a restrictive or obstructive condition
- Pulmonary fibrosis
The correct answer is 4- pulmonary fibrosis
The first thing we want to look at is the FEV1/FVC% and FEV1, both are normal so there is no obstructive disorder. An abnormal FEV1/FVC% is<70, an abnormal FEV1 is below 80.
After we look a the FEV1FVC% and FEV1 look at the SVC and FVC, both are low indicating a restrictive disorder. The only restrictive disorder that is an option is pulmonary fibrosis.
