My Mom has emphysema and is on oxygen 24/7. She recently contracted
pneumonia and is hospitalized. She is now on 6l of oxygen and still
cannot walk without distress. She is 74 yrs. old. I fear that this
is the end. Her oxygen levels are fluctuating from 83-88 on 6l of
oxygen. How low is too low on the oxygen levels? I am very
frightened about all this.
