I see mostly very short CA's and am not sure what to make of them, so Ive also added a close up on one of the CA's for you thoughts on what it is?
Unless you are having problems when the pressure gets high, such as a painful amount of aerophagia (air swallowing), I would suggest increasing the Minimum Pressure so it becomes 1 to 3 cm H2O lower than your 95% pressure, but no need to make the jump all at once, can move Minimum Pressure setting to 6 and then perhaps gradually raise it higher. (Alternatively, some would prefer a minimum Pressure setting about 4 or 5 lower than the 95% pressure, and others prefer a Minimum Pressure which is about the same as their typical 95% pressure.)
The 95 percentile pressure is the pressure you were at or lower for at least 95% of the night (session). It is also the pressure you were at or higher for at least 5% of the night.
I don't understand why SleepyHead is reporting mostly Obstructive Apneas according to its event pie chart, but is not including a row for Obstructive Apneas in the event flag timeline. Perhaps a SH bug?
May be good to double check what the data looks like using ResScan.
Often, new PAPers will see a significant number of CA events in the early weeks and months of PAP therapy, and usually the number of CA events will decline over time.
An "ASV" model of CPAP machine would be able to treat central apneas (as well as obstructive apneas). If after a month or two of using the machine, if the CAI (Central Apnea Index) was at least 5.0 and was the majority component of the AHI, then perhaps an ASV (Adaptive Servo Ventilator) machine would be covered by most insurance companies. (I've heard that some insurance companies will not approve coverage for ASV machines unless the CAI when using a non-ASV machine is at least 10 or 15.)
The point is only that your CAI is likely to continue improving as your body gets accustomed to breathing under pressure, and your CAI is already far lower (at least on the one night shown in the posted data) than what would be commonly considered to indicate an ASV machine may be needed.
One thing that sometimes causes an increase in the CAI is EPR. After a few more weeks with EPR of 2, if the CAI has not continued to improve, you might want to try lowering EPR to 1 or zero for a while, to see if in your case this further reduces the CAI.
