Abstract
A coupling for use in a system (2) for communicating a flow of gas from a pressure generating device (4) to an airway of a patient includes a first portion (16, 16′, 16″) adapted to be coupled in fluid communication with the pressure generating device and a second portion (10) selectively coupled to the first portion. The second portion is adapted to be coupled in fluid communication with the airway of the patient. At least one of the first portion and the second portion includes an illuminated portion (18, 20), the illuminated portion being adapted to be visible to a patient when the first and second portions are uncoupled and adapted to be not visible to a user when the first and second portions are coupled. The illuminated portion assists a user in locating and recoupling the first and second portions of the coupling in a darkened room.
