I wonder if someone can explain/reassure me about this...
I've recently escaped from hospital after my first admission with my asthma on Monday - although I've always had asthma it's only in the last three weeks or so it's got out of control and been described as severe and things spiralled to me needing in-hospital treatment.
Whilst I was in hospital, they kept a check on my blood oxygen levels both with a sensor on my finger and through taking blood gasses (??) from my wrist (got a mega bruise there now) - and it was concerns over my levels that had them keep me in for longer. On oxygen (dependent on the percentage) my oxygen levels were 98-100%, but off oxygen they were stubbornly sat at 92% - and because this didn't change despite the treatment, they discharged me at that level (my peak flows are also low - currently about 70% of where they should be (although they were about 40% when I was admitted so that's an improvement).
The thing is, this has left me really really worried, and I have no explanation - I'm going to try and go and see the GP who had me admitted next week as I think she'll be helpful but not having any answers is leaving me very anxious - what does a low oxygen level mean, does it matter, might it explain why I'm so breathless and feel generally dozy (as in sleepy but not tired)? Is this 'normal' following a severe asthma attack?
