[Pressure] Pressure increase after interesting flow rates

[MisterM]

I have a dreamstation auto, use heated hose and humidifier, ResMed P10 nasal pillows.

Machine settings are 9.0cm floor, 13cm ceiling, 20min ramp from 7cm, A-Flex is set at 2.

Last night's AHI was the best ever but aerophagia side effects were horrible.

Could someone look at the general zoomed in area and then the more zoomed in area and give me an idea of what was going on at the time the pressure increased so much? 

Thanks

Looks like the pressure started rising as a result of the machine sensing a snore (VS). Pressure will increase due to obstructive events, flow limitations, and snores.
