I've only had Asthma for about 3 years and suffered a very severe attack 2 years ago that put me in hospital for 12 days. Since then i've had about 2 or 3 less severe attacks each year since triggered by colds/flu/viruses etc but this year i must have had 7 'episodes'.
Earlier this year i purchased an oximeter which you attach to your finger to measure the oxygen levels in your blood. I purchased it because i was worried that during attacks that as well as SOB, tight chest etc i was feeling dizzy and suffering from bad headaches. Most of my attacks occur first thing in the morning and i started to record my O2 readings as well as my PF's.
In the last few weeks my PF's have been down to 320 (best 600) but with O2 readings as low as 80% at the worst. The O2 readings do recover to the high 80's about half an hour of taking reliever. If they had stayed at 80% i would have gone to A &E.
Does anyone else record O2 levels and what are your experiences? Are the low levels and headaches something to worry about?
