First Upload of OSCAR Data - Help Decipher? - Diggers4pg - 05-12-2019 Below is the first upload of my OSCAR data.  I am certainly doing way better on AHI vs. my sleep study (it was 77) and I know there is an adjustment period, which I am only a week into.  As suggested, I changed my min pressure last night.  My previous 90% was in the 11 range.   Any help analyzing would be greatly appreciated! Note that the F12 didn't work for me, so I used Snipit. RE: First Upload of OSCAR Data - Help Decipher? - Gideon - 05-12-2019 Welcome to the forum. A small correction to your screen print. You have zoomed in to a view of the tail portion of an exhale that is about .5 seconds long. Please show the full night. (rt click on a graph title the zoom to 100% view) Thanks You can try a Flex of 2 and see if that helps your hypopneas. RE: First Upload of OSCAR Data - Help Decipher? - Diggers4pg - 05-12-2019 Is this now correct?  Thank you for the help RE: First Upload of OSCAR Data - Help Decipher? - Gideon - 05-12-2019 First, your numbers are pretty good, I think they can be better. Not included in your AHI I see a lot of Snores, Flow Limitations, and RERAs.  RERAs are defined as a series of Flow Limitations followed by an arousal. Arousals are bad because they disrupt sleep. What are Flow Limitations? Event Definition Apnea, Hypopnea, Flow Limitation Apnea: 80% to 100% reduction in airflow for >= 10 seconds Hypopnea: 50% to 80% reduction in airflow for >= 10 seconds Flow Limitation: <50% reduction in airflow for >= 10 seconds These events may be either Obstructive or Central in nature They represent different degrees of similar events. All of these may be disruptive. While Central Hypopneas are important in diagnosing Central.Mixed.Complex apnea they are not monitored in most Sleep Studies. Treatment: Obstructive Apnea is treated by raising pressure, specifically exhale pressure.  (Note that with basic CPAP Pressure = Inhale Pressure = Exhale Pressure). I would like you to bump your min pressure to 8. I would also like you to increase your Flex to 2, This should help your Hypopneas, Snores, Flow Limitations, and RERAs.    I suspect that you will require more pressure but let's see what this does first. RE: First Upload of OSCAR Data - Help Decipher? - Diggers4pg - 05-12-2019 Thank you!  I will reset tonight.
