An extendable airflow restriction system is described herein which may be used to treat various disorders by creating expiratory positive airway pressure while providing for patient comfort regardless of the patients anatomical variances. Such a device may be removably secured within the patients mouth and may include an extendable member which may project to urge the patients upper lip towards the nostrils to restrict airflow. Moreover, the restriction device may include one or more sensors to detect the patients respiration activity such that the device may be actuated to correspond to the patients exhalation.
