@mcjooce2 I am pretty sure autosense means that the machine senses your breathing and decreases the pressure so you don’t struggle to exhale. I hear my motor wind up and down with each breath. There is still a setting in the configuration area of the setup menu to set the pressure (both max pressure and let-off or whatever it is called). These are in a hidden menu - not the normal end user settings. Older machines would give continuous pressure but now I think the new machines are BIPAP even though they are still commonly referred to as CPAP machines.
Too little pressure it is not effective but too much pressure can be bad too because you might not be able to exhale the CO2 in your lungs. It is probably less of a risk with the BIPAP machines but I would consider doing the sleep studies so they can dial in the correct pressure for you. They will monitor your brainwaves and make sure you are getting into deep sleep. Guessing at your setting would be a crapshoot and it can be hard to adapt to the thing in the best circumstances. Going by how you feel and wondering if it is even working will probably be hard to do and take a long time. You can get the scrip and send it to
cpap.com to buy new direct (and on-going replacement accessories) or grab a used one on Craigslist and set it up yourself. Don’t mess with the medical supply companies they will try to steer you toward unless insurance is covering it.
For me it was life changing. I had no idea how bad I needed it. I wish I had done it years ago. I could not put a price on quality sleep.
