THANK YOU SOOOO much!!!! My AirSense 10 "broke" 2 days ago and a friend gave me an identical machine that she has not used. I have made numerous calls to doctors' offices and DME providers to figure out how to1.fix mine or 2. new script or 3 new machine or 4fix needed part and struck out on all accounts. I am going out of town in less than a week. Have used cpap for sleep for well OVER 20+ years but have never needed to even know the pressure not to mention having to change it. You are an answer to my prayers! As a retired RN, I have never had a need for this information. But it has been so helpful, I've watched it 3 times. I did change the pressure to mine and cleared her settings. But it had an option to go back to factory settings. I didn't do that for fear of changing what i did alter. Should i change the factory default ?

Thanks so much for the information of how to make clinical pressure adjustment settings...etc.
