A member asked:
Could obstructive sleep apnea cause rv, tlc, and/or rv/tlc ratio to come back higher on pft?
3 doctors weighed in across 2 answers
I agree with Dr. Le as obstuctive sleep apnea alone would only affect the very high portion of the airways. Elevated levels of TLC& RV indicate overinflation and air trapping in the lungs. I think COPD and obesity combined with obstructive sleep apnea could give these values. A pulmonologist would be best to answer your question.
