I was advised by my sister (nurse) to buy a pulse oximeter to home monitor levels of blood oxygen as COVID-19 negatively affects this. I’m told it should be about 95 and mine was. As a matter of interest I did the back breathing we practise at Tai Chi and it went up to 98. Proof the back breathing works on blood oxygen levels.
