My COPD causes me to live with 88-92% at rest and the need for O2 to keep sats up to walk. 'Course I live at 6500' altitude where most run at 96% normally. I do know my finger oximeter is not really equal to blood. I understand the the circulation has issues with Covid so finger measurements might be quite wrong. But I'm no expert.

Yes, that's why we can't get a good reading with cold fingers.
