Abstract
A improved nasal mask is disclosed for delivering CPAP therapy to patients. The nasal mask has a sliding engagement to the headgear. The sliding engagement allows substantial relative lateral movement eg: when face is distorted from sleeping on side, while still providing adequate compressive force to avoid side leakage. The sliding engagement also allows easy release from the headgear.
