Abstract

A device treats sleep apnea by supplying pressurized air to the nasal passages of a user through a connection device connected to said control device through a hose. The device includes a blower which pressurizes air and which supplies the pressurized air to the connection device, and a control device adapted to control the pressure level supplied by the generating device. The control device incudes a ramp generating device adapted to selectively control the generating device to generate pressurized air at a pressure level which increases for a preset time to a preset prescribed pressure level, and an override device which, when actuated, overrides the ramp generating device and which controls the generating device to immediately generate pressurized air at the preset prescribed pressure level.
