Hi Ellsworth, welcome to the forum!
The machine may be autotitrating but, like Archangle wrote, your breathing may show characteristics of Flow Limitation, causing the machine to raise the pressure.
If it is not too late, I suggest exchanging the machine for the new A10 AutoSet For Her model, so you can try the gentler AutoSet For Her therapy mode.
The A10 AutoSet For Her (unlike the S9 AutoSet For Her) has 3 therapy modes, fixed-pressure CPAP therapy mode, standard AutoSet therapy mode, and the new gentle AutoSet For Her therapy mode. The A10 AutoSet for Her has everything the standard A10 AutoSet has, plus more, so it is like three machines in one.
The AutoSet For Her therapy mode raises the pressure more gently. It also includes the added feature that the Minimum Pressure setting will auto-adjust if needed, to better maintain an adequate therapy pressure.
The A10 AutoSet For Her model is the only ResMed model which reports Respiration Effort-Related Arousal (RERA) events. (RERAs are arousals caused by respiratory effort but RERAs do not qualify as hypopneas and are not counted in the AHI because the reduction in breathing was not at least 50%, or the Oxygen desaturation during the RERA was not deep enough.)
Take care,
