I have a question concerning my new ResMed AirSense 10 AutoSet Elite in comparison to my previous Löwenstein Medical Prisma Smart CPAP .
I 've been using a CPAP for 4 months now, with a Löwenstein Medical Prisma Smart, with an autoset of 4 to 10 (no ramp, no other options activated). The mask I use is the Fisher & Paykel Evora Nasal Mask with Headgea.
Everything was fine with my Löwenstein, but as I'm moving out of the country, I had to buy a new machine (the Lowenstein one is a rental) .
I tried the Resmed Airsense 10 last night, with the same setup "autoset, 4 to 10" but I felt the pressure much strongly. My mask was having more leakage and I experience for the first time since starting using a CPAP , a LOT of bloating (a lot of air in my stomach, which kept waking me up during the night). It's the exact same setting so I don't understand why, even on 4 , it feels like a much stronger airflow. I feel that my lungs are constantly inflated.
Also, I don't know whether that could give more info, generally with the Lowenstein, I was on an average of 5/5.5 to correct my apnea (I'm quite petite, but have apnea because I'm hyperlaxe, so i don't need a lot of pressure) but tonight with the Resmed 10 my average was at 7.8.
I asked my husband to try the two machines side by side, to see if he also noticed a difference and he did. The airflow on 4 feels stronger on the Resmed and it makes you breath harder. It's also more difficult to replace the mask on my nose correctly as the airflow pushes/inflates the silicone of the mask more than with the Lowenstein CPAP.
What could be the reason for experiencing so much bloating (which like as said, never happened to me before), plus this feeling of inflated lungs, even thought the settings are the same on the two machines?
Thank you for your help!
