I have discovered from having these used on me, that cold hands seem to make the reading drop for some reason. When I know I am having my oxygen levels checked, I always warm my hands and take deep breaths beforehand while I am waiting, to try and give the best reading.

This can certainly increase the figures , but do you want the best[i reading or a [i]true] one?
We've had one for a long time. Also, a peak flow meter for lung capacity (my son has asthma). The only thing with that, is that you have to know regular healthy readings, so you know if it is starting to decrease.
The useful thing with the peak flow, is that it would tell you earlier, before the oxygen starts dropping. If you are getting down to 92%, you are already in some trouble.
Preferably regularly, jno... as the averages are different for different people and you really want to see any decline ASAP, as a warning at least. Both these will give you an idea, before you start to feel unwell.
Did a few checks to establish 'reference levels' and kept a note with the gadget - have used a couple of times since when one of us was feeling poorly - a reassuringly normal reading was useful.
I've been meaning to get one of these for ages. With a severe/extremely severe COPD diagnosis a year ago I wonder why neither my doctor nor consultant have mentioned it. Probably have a job to get one now as so many will be buying them.
