nothings working?

so my boyfriend has sleep apnea. he got a cpap like 9 months ago i think. and he STILL isnt waking up great. i literally need to spend about 1 hour waking him up, he’s tol d me to try pushing him off the bed, pouring water on him etc etc and nothing will work. hw’s got a tracker thingy that we check in the morning and 95% of the time the mask fit is right, the seal is right, theres no leaks and whatever else it tells u. he also sometimes takes the mask off in his sleep but even when he doesnt he still wont wake up properly. ive come into the lpunge hours after work has started to see him asleep on the kitchen floor. when i was in labour he couldnt even wake up. i dont know what to do with him anymore. its putting a huge strain on our relationship. what are some things we could tey?

things we’ve already tried is:

• like 5 different masks
• going to bed earlier
• no screens befire bed
• no caffeine before bed
