I just completed the first download of memory CPAP card and the report showed that I still have many episodes of OSA and CPAP is working. But after two recent formal sleep studies, which only indicated OSA, I am now showing central sleep apnea, 16 out of 19 days, either appearing isolated or overlapping with OSA. I have cardiac MVD without any other diagnoses. Why would this show now? I use less nitro spray,( last extra spray weeks ago),I feel less tired, but for the past 3 weeks I now have more PVCs despite wearing same 0.16mg nitro patch daily. Joan.
It depends on how many central events you're having. If your obstructive episodes are significantly less, then one or two central events is not too concerning. However, you should talk with your sleep doctor about this to further fine-tune your treatment options.
