Use of an OXIMETER

Franbern, I have been advised that a reading of 93 can be expected for someone (me) with lung conditions. It's when it constantly remains lower, that it's best to seek help.

Unfortunately, unless you check you can be unaware of a drop.
I was having an angiogram, when the consultant said my levels were causing concern. I was totally unaware, they had dropped, I didn't feel any different. ?

I have one; and was glad I did last week when I went into AF. When I rang the doc I was able to tell her my pulse rate was veering between 46 and 168; and sats below 80% - I felt very unwell and could hardly stand up.

It stopped spontaneously thank goodness; but it was useful to have accurate info for the doc so she could make a judgement as to what to do and the pattern of my AF bouts.

We have had one for a while but my wife has difficulty getting it to register anything. She is very slim - thin really - has permanently cold hands, and is virtually impossible to draw blood from for testing. Since two courses of chemotherapy she's had peripheral neuropathy, so that may be relevant.
I gather that warming the hands and using the pulse-ox instrument in a darkened room (it uses light transmission to measure) is likely to improve matters.

I had a similar problem and rang the manufacturers who told me to use my thumb - which does work.

Thanks Luckygirl, we'll try that.
