So my new Piko arrived today. It's even smaller than I thought which is great.
Problem is, I can't get the damn thing to work properly!
1) I can't seem to set the FEV1 zone. Managed the PF but every time I do what the manual says all I can do is reset the max PF, not the FEV1, and it has some odd ideas about what my best is.
2) More importantly, I can't get consistent readings! I can't even work out whether it's consistent with the manual meter as the readings are all over the place - one moment I have giant horse lungs and the next I'm apparently having an asthma attack and ought to be on the floor, and I can't even work out whether the 'horse lungs' one might be close to correct (my readings may tend to be high but I really doubt that even I can do 800 PF and over 4 FEV1 with no reliever and a tight chest, esp judging by my last sets of 'official' FEV1 results).
This may well be due to my crappy technique (remembering the havoc I caused last time I did spirometry at the hospital, but even they were at least vaguely in line with what I could be expected to do at that point). But just wondering if it is all me or if anyone else has had this, and if so what you did.
3)Also, I can't work out if I'm doing something different but this evening it kept beeping at me to tell me my technique was wrong, but it was fine this morning...not sure what's changed!
Would it be worth asking the asthma nurse at my surgery to give me a lesson on how to use this thing? I don't want to waste her time but I do want to get to grips with this - don't know if she'd really be familiar with it though.
