Abstract: A quick disconnect fitting, that is operable with one hand, is provided for connection of a endotracheal tube and an artificial breathing apparatus output tube. The fitting is preferably a rigid body member having a artificial breathing apparatus input member, a endotracheal output member, and a movable piston or plunger for manual extraction of the endotracheal tube from the endotracheal output member. A finger support member can be provided to grip with at least one finger to obtain additional leverage to depress the plunger with the palm of a user's hand. Fluid communication is always maintained from position 1 to position 2 were complete disconnection of the endotracheal tube is achieved.
