805 nasal mask

A CPAP nasal mask for obstructive sleep apnea therapy. The silicone cushion conforms to the nasal contour, 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 sampling port is available for pressure or EtCO₂ measurement. The compact profile and open field of view suit users who prefer a lighter, less intrusive fit compared to a full face mask.
