DLCO test determines how effectively gases are exchanged between the blood and airways in the lungs. Pats w emphysema have lower DLCO results indicated by a reduced ability to take up oxygen.

Guys for this question, is'nt a normal DLCO 75-120%? Therfore a value of >60% should be interpreted as low?

Thoughts?
