I was recently diagnosed with very severe OSA, and I got my CPAP machine last Tuesday. My pressure is 18 and I have a FF mask. Last night, something changed about the airflow! Before, when the airflow started, I could feel the mask kind of "fill up" with air, and my cheeks would puff out. I even heard a "whoosh" sound. It was almost like it was making it's own little atmosphere inside the mask, and I could feel that the airpressure was higher. Last night, it just felt like wind blowing in my face, without the whoosh or the puffing or anything. I checked all over for leaks, but there weren't any, even around my mask. I'm so new to this, I'm not sure what to think. Any suggestions on what could have changed? I think I still slept okay, but at this stage it's hard to tell because I'm still pretty tired all the time. Thanks!
