Good to hear from you also. The second chart was with the Bipap set on S mode. When I look at my history, my AHI was much higher than usual almost every time I tried the Bipap on S mode. Interestingly, they set the Bipap on S mode during the titration study and my AHIs were very high.
I will post a copy of my stat history.
I am most comfortable with Auto, even with my IPAP set to 21 and my EPAP set to 11 with PS set at 3. With these settings, my AHI is almost always under 5. I am still on 02 and set at one liter. This seems like a good combination because my 02 is fine and my apneas are low.
I have a unilateral elevated hemidiaphragm caused by my severe stenosis at C 3, 4, & 6. This is rare, and doctors do not know how to treat it. If things get worse, I can get a phrenic nerve stimulator (PNS) pacemaker!
With such high CA and Complex Apane during my titration study, I would think that Medicare would pay for a ResMed ASV. However, the MD who rated the titration study never mentioned one. I think they are worried that Medicare will not pay for an ASV machine. The cheapest one I can find online is $3,000.
