This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is studying how continuous positive airway pressure (CPAP) machines work by testing different exhaust port sizes and pressure settings. Researchers want to measure how much of your own exhaled breath you breathe back in with different machine configurations, and how this affects the oxygen levels in your blood. The goal is to understand which settings are safest and most effective for people with obstructive sleep apnea.
Some CPAP machines may allow you to re-breathe some of your own exhaled air, which could reduce the oxygen you're getting. This study exists to measure how much this happens with different machine settings and to help doctors recommend the best configurations for treating sleep apnea.

You will wear your CPAP mask while the researchers test it with 11 different combinations of machine settings—changing both the pressure level and exhaust port size. During these sessions, monitors will measure the oxygen and carbon dioxide levels in your blood while you're awake and asleep. The study involves testing these different settings to compare how they affect your oxygen levels, helping researchers understand which configurations work best.
