I have questions on this also. I’m 63 and just diagnosed. Put on 2L of Oxygen, with no instructions on when I’m supposed to use. Just when I get low? Always? Sitting, I’m at 90 to 92. Upon waking, I’m at 93 – always. I feel fine. Moving around the house I drop to low 80’s. Exerting myself, bending, brushing teeth or carrying something – I go to low 70’s. I recover quickly though – so I’ve never really used the oxygen except for odd occurrences. I pay attention and adjust to bring my levels back up. I wonder if I’m doing damage sometimes though. Does the low saturation take a while to do damage, or is it immediate.
