With my NHS respiratory appointment months away, I paid for a private consultation today and puffing into machine yielded what I think he said was 73% or thereabouts... I asked what stage and he said moderate and mild, he used both terms... so I'm still not much more knowledgeable.... I suppose if he writes a report I'll know.
It was a lot to take in and you don't always think straight in there.
So questions is ... What stage would around 70% be please???
