Hi, I wanted to ask a question about peak flow and spirometry. Just for some background, I'm a 40 year old nonsmoker. Last year my Dad sadly died having suffered with IPF. He was still relatively young at 65. His own mother died aged 51 having had lung cancer. These things made me wonder about my own lungs and whether there is some genetic weakness there.
My 17 year old daughter has asthma so has assessments every so often and I've always wondered how much I could blow out into a peak flow tube if I tried. I asked the nurse if I could try and found that I had quite a low one at 320, me being 5" 6. I find it hard to breathe while walking and talking at the same time and had always put this down to not being sporty. I definitely started to wonder if this was normal after watching my Dad struggle during his illness.
Anyway, I went to the GP and kept a peal flow diary for two weeks. There was not much variation but it was always around 300, sometimes lower, sometimes higher. Then she sent me for spirometry which I had done yesterday. The man doing it told me that I had just passed the threshold for normal, so I was not given an inhaler to try for reversibility testing.
I suppose this hasn't left me feeling overly confident about my lungs. To have a low peak flow and now only just scrape through into the normal category doesn't seem brilliant to me. Does anyone know what this means for my general health? I am not overweight but I've never been particularly active. I don't like sitting for long periods, and I like to go walking, but that's about it. I've always found it hard to do more than that because I can't get enough air in.
Sorry to go on so long, I just am unsure what to think.
