This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether the type of mask you wear during adaptive servo ventilation (ASV) treatment affects how well you sleep. ASV is a breathing machine used to treat central sleep apnea — a condition where your breathing repeatedly stops during sleep. The trial will compare a nose-only mask with a mask that covers both your nose and mouth to see which one helps you sleep better and more efficiently.
Many people with central sleep apnea don't get better with standard CPAP machines and need to move on to this treatment instead. However, doctors don't yet have clear guidance on which mask type works best for each patient. This study will help answer that question so doctors can recommend the right mask choice right away.
You will spend two nights in the sleep lab wearing different masks. On one night you'll wear a nose-only mask, and on the other night you'll wear a nose-and-mouth mask. During both nights, doctors will monitor your sleep using a sleep study to see how well you sleep with each type of mask. The order of which mask you wear first will be randomly assigned.
