Hi Kaz,

Myself, I am finding as I get more used to the Piko-1 and the slightly different technique you have to use, the values seem to be closer. I do prefer having the FEV1 reading as well, as my peak flow often does not drop in prediction of an acute attack, and I think maybe my FEV1 might start to drop sooner, and relate more closely to how I am clinically, which would enable me to better judge how I am (as my perception of how bad I am seems to be a little blunted these days) and may give me more warning of my usually very sudden onset acute attacks. I haven't actually tested this out yet, as I haven't had a bad acute attack since I got it, but that's the theory!

For most people, their peak flow will usually drop in anticipation of an acute attack, often for several days beforehand. If this is the case, then an ordinary mini-Wright peak flow meter should be quite sufficient, and a Piko-1 may just add to the confusion and give folks more numbers to worry about!

I do think it's probably a matter of individual preference; in terms of the accuracy of the results, I believe the Piko-1 has been fairly well validated in terms of clinical trials, so I am at a loss to explain the disparity you are experiencing, unless your technique is not quite right. Have you had your technique checked by someone who is familiar with the Piko-1?

If you are more comfortable with the mini-Wright and your consultant prefers it, I think I would stick to that!

Hope this helps

I find the mini-wright difficult to blow into...the mouthpiece is HUGE!
