Just returned from my first visit to the Respiratory Lab having only been diagnosed with ""Probable Asthma"" after a rush to A & E by ambulance and being kept in for a week. As Ive mentioned elsewhere is was all a bit of a shock at 57.
Anyway tests done and the worse bit I think was no meds since last night and the lab being at the far end of the hospital!
Reversibility showed a peak flow jump from 400 to 545 and all other measurements improved after the salbutamol - so final diagnosis I do have asthma and not COPD (would have been a bit of bad luck as Ive never smoked in my life).
Had an appointment with the respiratory nurse at the hospital afterwards and she spend a fair amount of time explaining the results to me and talking me through my meds and how to go forward.
All in all a really good experience and I now feel as if I know what is happening and that I am in control - which is as it should be.
being referred to Respiratory consultant, what to expect?
Respiratory Consultant wants me to come off asthma meds!
Really positive respiratory review
