My family has a history of respiratory issues, we live at 4600 ft in Utah, she just returned from a trip to Shadow mountain which is at even higher elevation and her allergies (so we think) flared. One day after coming home she is breathing hard, chest hurts and her oxygen while sleeping is currently bouncing between 89=90 using oxyometer on her fore finger (on her middle finger is was 85-88), our insurance is horrible, our deductible is $8000 out of pocket before any help kicks in so if you think that what I am doing, which is, gave her benedryl, flonase nasal spray, and using provental inhaler while monitoring her oxygen is good hoping it clears up now she is back home, if so, what is the lowest while asleep her oxygen should be and while awake? Thank you for your response Sandy Dawson
