Description

technical field [0001] The present invention relates to a mask system for positive pressure ventilation of sleep-disordered breathing. In particular, the present invention relates to a low cost mask system. Background technique [0002] Obstructive sleep apnea (OSA) is a condition characterized by repeated obstruction of the upper airway, often leading to oxygen desaturation and arousal from sleep. The typical daytime presentation is extreme sleepiness, but other symptoms such as non-restorative sleep, lack of concentration, and fatigue are commonly reported (Sleep-Related Breathing Disorders in Adults - AASM Thematic Study Group, sleep 22, 1999). [0003] Sullivan in US Patent 4,944,310 teaches the use of nasal continuous positive airway pressure (CPAP) to treat OSA. Other developments are taught in US Patents 5,704,345, 6,029,665 and 6,363,933. [0004] Nasal CPAP systems typically include a flow generator, air tubing, and a patient interface (eg, a nasal mask). The ...
