Q

Which has a normal diffusing capacity for carbon monoxide(DLco)? Asthma, COPD, restrictive, fibrotic lung disease or extra thoracic restriction?

A

Asthma has a normal diffusing capacity of carbon monoxide because the alveoli are unaffected. By contrast COPD and restrictive/fibrotic lung diseases will have a decreased DLCO because of alveoli or destroyed and unable for gas exchange.

Q

Cystic fibrosis Inheritance, gene, sx ?

A
