Abstract

A system is disclosed for nasal delivery of Continuous Positive Airway Pressure to a user. The system includes a variable speed fan unit to pressurize the gases, and a humidification unit to provide a controllable level of humidity to the gases. The pressurized humidified gases are transported through a conduit to the user, and arc delivered through a nasal mask to the nasal passages. The oral cavity is sealed against 'mouth leak' by insertion of a sealed mouthpiece. The mouthpiece includes an intra-oral sealing means and an extra-oral sealing means substantially sealing the oral cavity of said user. The extra-oral sealing means may be adjusted into one of two conditions, a first condition when said mouthpiece is inserted into said user's mouth being, substantially unengaged with said user's face, and a second condition when correctly positioned in said user's mouth being substantially engaged with said user's face and under compression thereupon.
