Thank you! He seems not to.be able to get used to the cPAP. He has tried different masks etc but so far no success I got him an Oura ring a few years ago. According to the ring data he gets no deep sleep ever. Mostly REM and light We are trying to implement more movement during the day. Etc. to help with his sleep. But he’s not the best when it comes to understand the consequences long term Thank you
