Abstract
A respiratory mask includes a mask body with a perimeter. The mask has a use position wherein the mask body covers at least the mouth and nose and the perimeter is in contact with the face surrounding at least the mouth and nose. At least one ultrasonic sensor is supported on the mask body in detecting proximity to the perimeter. The ultrasonic sensor is operable to detect ultrasound. The ultrasonic sensor allows leakage around the perimeter of the mask body to be detected.
