I currently have a Airsense 10 Elite

I had the same cpap machine for about 14 years. When I first got it I had a max pressure at 10. I did not take care of it as well as I should have and did not use filters after I used what I had. This was my fault. Well my father got a new machine and gave me his old one. He had it a few years but it was still way newer than mine. Well I set the new machine to 10 as my old machine was. For the last couple months or so I have had stomach bloating and tightness. I never had bloating issues with my other machine. My first question is could my old machine be so dirty inside that even though it was set to 10, it wasn't actually putting out that pressure? My second question is could the pressure of 10 on the new machine be to high and causing my bloating/tightness? It doesn't go away. Has anyone else had this issue? Any help would be very appreciated.
