Hi rickresmed, welcome to the forum.
What me50 said, but you might need to make a few more posts before your membership status will be upgraded and you will be able to post an attachment or a link to a file.
What therapy mode is your machine in (Auto or S?), and what is the PS set to? (PS, Pressure Support, is the difference between the exhale pressure setting versus the inhale pressure setting.)
It is true that the CAI (average number of central apnea events per hour) may improve as you gradually become accustomed to the high pressures, especially if your earlier CPAP pressures were lower. Also, the OAI (average number of obstructive apnea events per hour) may improve as we learn to minimize mask leaks and mouth leaks.
But, of course, I would be concerned if my CAI was as high as 39.2, and perhaps I would call my doctor right away so he could look at the data in the SD card as soon as possible.
The two things which usually lower the CAI are (1) lowering the PS and (2) lowering the Max IPAP.
One of the things which often allows the pressure settings to be lowered is if we can ensure that we are never sleeping flat on our back.
During overnight lab titrations, we are usually asked to sleep at least part of the night flat on our back, because that is usually the worst case sleep position for causing Obstructive Sleep Apnea.
If we can ensure that we will never be sleeping flat on our back, then it is likely our pressure needs will be lower. And the lower pressure may significantly lower the CAI.
