I am on oxygen at night and have been for about 5 years. I sleep fine without it but the doctor said this is a way to insure my organs are getting enough oxygen and will last longer. I never go without my oxygen at night. BUT ... there are some people who say I should be on oxygen all the time. I don't think so. When I am sitting at my desk or watching TV without oxygen, my oxygen level stays way above 90, usually about 96. The only time my oxygen drops is when I am walking!
I have portable oxygen I can use while walking but way should I use it while I am sitting?
