Yup, me too. My first machine was kind of outdated and beat up, and they could never really get it to work right. Then they got bought out, and I got a new machine. The difference is night and day. No settings needed. You put on the mask, turn it on, and bye! It supposedly had some form of AI in it. I don't know, but it quickly self-adjusts to my breathing as the night progresses, and all I have to do is keep the filters clean. Makes an amazing difference in my sleeping. It is called an NIV, or non-invasive ventilator. It's a Lowenstein Luisa LM150TD. It works as good as the big fancy one at the hospital!
