At my son's clinic appointment this week his pulse ox never got above 95. My son has never had a pulse ox reading below 99. Should I be concerned? What is considered in the normal pulse ox range? What can cause a lower pulse ox reading? The pulse ox was one of the first things they did when we got there and then a couple of other weird things happened and I forgot to ask the doctor about it. I had one of those moments last night where I woke up in the middle of the night and suddenly remembered about the pulse ox number - I must have been dreaming about the clinic appointment or something!!! Now I'm paranoid that maybe it signifies something. But again, why wouldn't the doctor have mentioned it if it was any big deal?
