I've completed an oximetry study and will soon take the next step sleep study to determine whether I have OSA. I have my own SleepU device and would like to get a better idea of how to interpret my data in advance of my Dr reviewing my sleep study results. He tends to take a passive treatment philosophy, so I fear he may categorize my OSA as merely "mild", thus no treatment warranted. It may in fact be on the mild side by clinical criteria, but it does wake me up throughout most nights, so I hope some type of treatment is recommended. Also, even though my number of events may be in the mild category, some of the drops seem kind of low to me, with the recent lowest at 77%, if my device is accurate.
Anyway, the O2 Insight Pro software that goes with my SleepU device indicates around 4 events of ODI 3% per hour, and only maybe 2.6 events of ODI 4%. On the other hand, when I import that same data into OSCAR, it shows an SpO2 drop index of 7.31 - which I believe indicates 7.31 events per hour. But it's not clear to me what % drop benchmark that is using.
So my questions are:
1) What is the standard % benchmark for tallying OSA events per hour? It seems surprisingly difficult to find that detail online.
2) What % drop does the OSCAR software use to calculate its SpO2 drop index? I can't find an explanation of this with the documentation.
3) Do doctors take into account only the AHI when determining whether treatment is warranted? Or is the % drop also taken into account?
Thanks much!
