Testing mask types to reduce air leaks during sleep apnea treatment

This trial is testing whether switching mask types can reduce unwanted air leaks when using CPAP therapy for obstructive sleep apnea. Some people experience too much air leaking from their nasal mask during treatment, which can interfere with therapy effectiveness. The study compares two solutions: using a different mask that covers both nose and mouth, or using a chin strap with the standard nasal mask.

When CPAP air leaks around the mask instead of going into the airway, the treatment doesn't work as well and sleep quality suffers. This trial aims to find practical, simple solutions to help people whose current mask isn't sealing properly.
