摘要：
A breathing assistance apparatus includes an oral appliance and a valve arrangement. The oral appliance has an appliance body shaped to be at least partially positioned within the oral cavity of a user. The valve arrangement includes a valve body and a valve member. The valve body includes a valve airway in fluid communication with a user airway, and the valve member is positioned in the valve airway, movable between first and second positions at least in part as a result of airflow through the valve airway. The valve member at least partially obstructs the valve airway in the second position so that there is a differential resistance during inhalation and exhalation.
