SaO2 Nadir value question

Postby Guest » Sun Jan 07, 2007 8:41 am

I was hoping someone could explain the information provided to me from my sleep study. I had the absolutely the worst follow-up interview: the doctor was not prepared; could not explain the information; and walked out to get a copy of the study for me to look at while we spoke, but sent in his assisstant with the copy of the study and asked if I had any additional questions before I was released.

What is the SaO2 nadir value? What is a "good" SaO2 nadir value? My value was 84%. How does this relate to the oxygen saturation value? The thing that I really do not understand is how over the course of a study is how my O2 saturation level is 94% and I had a O2 level below 90% for 90 seconds, and I would an RDI of 28.

Thanks.

Blood Oxygen Saturation Level, while in hospital, of 95% causes concern.........below 90% normally requires intervention. A 'normal' person's O2 saturation level is normally between 98/100%

84% is not good, but some people here have gone down to 50%. Your 94% is probably an average level.

An RDI of 28 indicates moderate apnoea.............but close to severe (which starts at 30).

I think you need to put your foot down here. I certainly wouldn't pay the doctor for the type of attitude he displayed. you are entitled to a full explanation of everything on your sleep study report. You should demand it. Some of these 'give me your money and FO' type of clinician really get to me.

Best of luck.
