[Diagnosis] Confirming OA or CA using Airflow and Snore(effort)
#1
Confirming OA or CA using Airflow and Snore(effort)
Hi,

Is it possible to  differentiate CA and OA events in OSCAR just by looking at Airflow. Can I assume that the Snore graph in a way confirms effort  and thus confirms OA ? 

I understand that no Airflow with no effort confirms CA, My question is, does  ResMed Airsense 10 recognize snore by sound (microphone)  or by pressure differences  ? Would it be right to correlate snore with effort ?

RE: Confirming OA or CA using Airflow and Snore(effort)
i wondered the same thing when i got the machine, do i now have a microphone 24/7 recording everything in my house ?!

Here's one answer. Apparently it's a pressure sensor, but a microphone is also a pressure sensor that detects vibrations so i'm still not sure!

Thanks Narcil for your observations and comments about the microphone.
