Oxygen saturation level!!!

Oxygen saturation level!!!

Does oxygen saturation vary in lying and sitting position? I find my oxygen saturation 97% to 98% while Standing or seating. but while in bed or lying position it goes to 94 to 96%. is this normal? anyone have this experience. I have shortness of breath, & treating with seretide acculahoor & some other madicion. as my bronco provocation test came positive with 61% lung capacity. though x-ray & other test were normal.

Yes you will find variations throughout the day even if you spent the entire time in bed. It is normal. Any oximeter is only accurate to within 2% so there really is no significant change. Regards Rib

Hi Ant 64,

How are you? I see your oxygen is 95 - 98 sitting and 86 - 92 lying down. I was wondering are you on oxygen? H ow long have you had copd?

I am not sure when my acute Asthma evolved into COPD I think it was in the mid 1980's that I first started recognizing symptoms. I am not as yet on O2 preferring the present school of thought and that is taking a metered dose of your preventer through a spacer but I do know the time is coming when I will need to go on O2 so till then I will try and keep well

when I was ill in hospital, the nurse asked me to lie on a backrest to elevate the chest and head. It has made a difference. Plus I think, the mucus doesn't come up during the night. The oxygen level is somewhat depleted when lying down flat, they say.
