I am wondering how high your CPAP is set for. Is it up to 20 and does it go there? If it does, then what kind of mask do you use? I am open to suggestions. My machine is set for 15-20 so it as high as the machine goes. I live in an apartment so could not put a hook on the wall. I looked at the headboard and others and they keep the hose up high. When I am on my one side the hose is stretched all the way out so something that caused extra use would not work. As noted before, my doctor says that the machine is working as it is now, so I am not overly concerned that I do get that red frowning face.
