Well looks like I am going down the wrong road! Am trying to limit my time on the oxygen. But I have to keep my Sats over ninety which I can only do on the compactor! Right now at rest i.e. Sitting the level is 81. If I practice my yoga deep breathing exercise I can bring it up to 90 and over but don't feel I can breath like that all the time.
Am exercising. Bike weights and loosening exercise. With oxygen. But it's this not keeping the sat level up without it that worries me!
