Ans: D. A. and B.)Very Severe Obstructive Defect and Moderate restrictive defect.
- This patient has reduced FEV1 and FVC with a low FEV1/FVC ratio, consistent with an obstructive process.
- He also has a low TLC indicating he has a restrictive process as well. He would, therefore, be labeled as having a combined obstructive-restrictive defect.
- His obstructive defect would be classified as “very severe” based on his FEV1 of only 26% predicted while his restrictive process would be labeled as moderate given his TLC of 51% predicted.
