When I sit my o2 levels are 92-98 average 95. If I start to walk around ,get dressed, tidy kitchen etc it goes down very quickly to 78. I have just done a walk test and by walking very very slowly kept it above 90. They recommended pulmonary rehab ( had it 2 years ago) which I have just done 2 sessions. My gp and the walk test nurse seem to get twitchy if it drops below 90. I have bought an o2 finger monitor . In pulmonary rehab they don’t seem worried at all about a reading of 78 as long as I can still speak when exercising. I understand organs get damaged if the o2 goes below 88. I asked them how long I can exercise on levels below 88 and they don’t seem to know.
Does anyone have any knowledge or advice about this
Thanks jo
