APAP MAX Setting?

Post by RipVW » Tue Nov 20, 2007 7:22 pm

Okay, just wondering why one would not set the APAP max at the max, 20, since the machine automatically senses and delivers the pressure needed to deal with events. I know I need not set the minimum too low, below my prescribed titration, but don't really understand why you would need to limit the maximum pressure. Still learning . . . thanks!

Ted,
It really depends on the person. Some people can handle a large range, and some can only handle a small range.

For me setting the apap at the highest lead to the machine chasing snores. It would just stay at the top pressure most of the night. I have better numbers with it set as cpap on 9.5.

Too high a pressure can cause central apneas

Using the M-series auto w/C-Flex and James Skinner's Encore Pro Analyzer I have graphs to show that I have higher AHI at 8 and below and at 11 and above. My lowest number of hypopneas occurs at 8.5 and my lowest number of apneas is at 9.5. So I have set my range at 8.5 to 10.5. In fact I start getting nonresponsive apneas at 12.
