Breathing not Detected and Discrepancy in AHI on Oscar and Machine
A whopping 23.3% of my sleep last night is showing as "Breathing Not Detected" on Oscar.
What does this mean and should I be worried? The machine seemed to work perfectly all night as far I could remember.
Also, the AHI displayed on my Philip Respironics Dreamstation Machine is 8.7 while the AHI showing on Oscar is 3.7. This is fourth time of this happening.
Which one is more accurate?
I bought the Philip Respironics Dreamstation about 3 months ago so should still be under warranty.
RE: Breathing not Detected and Discrepancy in AHI on Oscar and Machine
On another forum we'd discussed DreamStation's and BND/breathing not detected. My take was BND is body not detected.

It strikes me odd that pressures was recorded throughout not the other parameters, EPAP, Leaks, Events, were not. thus the thought of a hardware failure dealing with the SD card.
OSCAR I am 100% sure, reported what it read, and did so accurately. But to me it looks like data is missing, the question is why?

troubleshooting.
do you have another machine you can read the SD card from?
Unfortunately I don't have another machine to read the SD Card from until the weekend.
However, I do have Dreammapper app installed on my phone, and I having the same AHI number as Oscar.
As the Dreammapper data is transferred through Bluetooth from the machine, I am inclined to believe that it is the machine showing inaccurate information.
