Abstract: An obstructive sleep apnea treatment device is disclosed herein. In embodiments the device eliminates the need for large peripheral equipment such as an air pump and hoses commonly associated with current treatment devices. In embodiments, the device is comprised of a main mask body component, at least one expiratory or exhalation pressure valve, at least one inspiratory or inhalation valve. In other embodiments, the device is further comprised of a forehead cushion component, a facial seal component, and an attachment component. In embodiments, the main mask body component is a nasal covering mask configured with a positive end expiratory adjustable pressure valve to generate a resistance on a patient's exhalation thus pressuring the nasal airways without the need of an air pump or electrical power source. Positive pressurization of the airways reduces the occurrence of apneas.
