I have had my Resvent Auto Pap for a week, and it hasn’t worked right yet. Every morning about 4:00 or 4:30, it starts losing pressure. It doesn’t matter how many hours I’ve had it on before then. It just barely blows at that time. It says it’s at level 6, but there’s no way it is. It’s not nearly as strong as when I go to sleep. I took it to the sleep clinic, but they ran it for 7 hours and couldn’t find any problems with it. Why would it be doing this at 4:00 every morning? It’s something to do with the time of morning obviously and not the number of hours. Has anyone else had this issue? It’s so frustrating that after a week I haven’t gotten a full night’s sleep yet. Thanks so much.
