FEV1 and FVC

Hi all

I recently had a mini lung function test at Brompton Hospital. I've received a copy of the letter the specialist has written to my own doctor and he has put that my FEV1 was 0.75 litres with an FVC of 1.4 litres.

Can anyone advise how I can interpret these, ie are they bad, reasonable or good? It also says my ACQ score is 5.16.

Any guidance anyone can provide (and I appreciate it is only guidance) would be very much appreciated.

Many thanks.

This should help

One thing I would say is you are as ill as you feel ill. Most of the time it can be put under control with the correct meds etc.

Be well


Thank you x


No problem I can never understand why the doctors seems to like to keep it all a mystery to us mere mortals :)
