Sharon and I were monitoring Elissa trying to keep her Oximeter at 97 which was a mistake on a flight. We tested our selves and found out we were only @ 89 oxygen saturation at 7500 foot cabin altitude. On the return flight we decided to try to maintain her @ 90+ which would save batteries even though we had to purchase 2 more for the flight back. I learned a lesson about traveling on oxygen.
