Is it normal to still snore mildly and softly while using a cpap ? my machine says i have about 2 events average per night, which is better than 25 i had prior. but i still snore very mildly some times. do i need bipap?

Is the snoring audible? You may need the mask to be tighter-it could be that the mask is leaking some so you should have that checked. It won’t make any difference-CPAP vs BiPAP-if the mask is leaking. It depends what the “events” are to determine the severity and whether or not it is acceptable to have them. But, make sure the mask is tight enough and not leaking significantly. Good luck!
