Yes, it is fine to try the minimum at 4 cm. However since there is some flow resistance in the hose and mask, you may find that a little restricting when you inhale deeply. It can lead to a suffocating feeling. It can do that during the night too if it decides you need no pressure, and going down to 4 cm may wake you up. Especially with the EPR on, more pressure is easier to breathe with than low pressure.
Yes, there is something called treatment emergent central apnea. I found it lasted longer than 1-2 weeks and was more like 8 weeks.
Autoset if fine to start with. Once you find a good pressure it may give more predictable results with a fixed CPAP pressure. The machine can tell the difference between a central apnea event and an obstructive one. It raises pressure in response to the obstructive one, and makes no change in response to the central ones. However I don't believe it is smart enough to distinguish between a hypopnea that is central in nature compared to a obstructive apnea, and I believe it raises pressure on all hypopnea events. That can lead to more central apnea events. If you fix the pressure then you can stop that response. But, to know what pressure to fix it at, you need to run it in auto for a while and look at how it behaves over the pressure range it goes to.
Yes, CPAP can help with UARS. ResMed makes an AirSense For Her machine that acts faster to raise pressure to address it. But, it still just uses pressure, and more pressure can increase the frequency of central events. I believe the AirSense 11 AutoSet has the For Her mode built into it as an option. In the AirSense 10 model you need to buy the For Her version.
This is bilevel machine which has more pressure and a higher differential between inhale and exhale pressure. They typically do not work much better than a standard APAP for central apnea. The best machine for central apnea is the AirCurve 10 ASV. It follows your breath to breath breathing and steps in to assist when you do not breathe normally.
