That is good news if your gases are ok! My blood gases are quite high and I do have hypercapnia and hypoxia. Drs say if anyone were to have my levels all of a sudden they would die. But my body has acclimated over time. My kidneys compensate by producing bicarbonate. The body is amazing.

Also when I was put on Oxygen in 2025 my O2 levels were in the 60's. I should not have lived with that but my body slowly adjusted. I must have been struggling with levels in the 80's for a long time not realizing it. Then it kept going down until it became critical and I was hospitalized. For some time I thought my Oximeter was inaccurate but it was not. So get a good high quality one and trust it and use it.

I wonder why some of you use Oxygen at night but not during the day. At night I can turn mine down to almost 1. During the day it has to be 2.5 or 3. Even so cannot do much that is physically active. Sitting feels the best.
