A CPAP full face mask for obstructive sleep apnea therapy. The silicone cushion conforms to the nose and mouth area, maintaining a stable seal without over-tightened headgear and minimizing leak-related pressure loss. Quiet-flow vent holes diffuse exhaled air to reduce noise while sustaining effective CO₂ washout. A built-in anti-asphyxia valve opens automatically if CPAP pressure is interrupted, allowing independent breathing. Two sampling ports — one on the elbow connector and one on the mask frame — provide flexibility for different clinical measurement needs.
