When I looked at Oscar for the history, I saw data for the worst and best AHI. I checked the difference in settings and found that the main difference was that the EPR was turned on after the first year. I was unaware of this as the technician had made the change. So I turned the EPR off and my AHI the first night was .2! So no doubt the EPR was not good for me. Any idea of why the EPR might increase the AHI?
I also notice that the AHI is highest in the first hour or so. I had been using ramp. I will try now without the ramp as it seems the ramp also increases the AHI. I thought these features were supposed to help but it looks like they don't work for me. Below are the graphs with EPR and without.
Thanks
