I was diagnosed 13 months ago with Emphysema. It was only up till last week that I was placed under the watchful eye of a COPD nurse at my GPs practice. Because it was a 12 monthly review she performed all the relevent tests to see how my condition had been. What she did ask me was did I have a Peak Flow Test Kit at home,I told her no to which she said I should have one to record twice daily these functions. She prescribed one for me and since then I have been recording functions. What I am asking here has anybody else got one of these and what are their recordings Mine are 200- 250 and I should be 618 for my range.
