sgomez63,

I was formally diagnosed with hypoxia (low blood oxygen) in 2021 one year after extensive pulmonary and cardiac testing could not find a cause for my SOB, fatigue, and near passing out in stores

I started using an oximeter to keep track of my oxygen levels at home. My oxygen level was 95% sitting, but would drop to the low 80's and high 70's with exertion. This dramatic change occurred after a mild case of Covid and the Covid shots in 2020 and 2021.

My sleep medicine doctor ordered a repeat sleep study and it documented the drops to 72% and I was put on home oxygen. Prior to this study the doctors kept telling me I had a defective oximeter, which was not the case.

Are you checking your blood oxygen level at home throughout the day? Do you see drops below 90%.
