Systems and methods for controlling breathing of a patient to maintain specified levels of CO2 in arterial blood. In one exemplary embodiment a respiratory conduit is configured to be coupled at one end to a patient interface device that is, in turn, coupled to the patient's breathing airway. The respiratory conduit is configured at the opposing end to be coupled to a pressurized air generating device. A control device is positioned in the respiratory conduit between the patient interface device and the pressurized air generating device and includes one or more vent apertures that allow a predetermined amount of exhaled air from the patient to escape from the respiratory conduit while retaining a predetermined fraction of the exhaled air to reintroduce to the patient during the next inhale. In this manner the system provides for a predetermined percentage of CO2 to be rebreathed by the patient.

An identifier for a conduit includes a first tag having a body with a first aperture formed therein for receiving the conduit and a first identifying feature, and a second tag having a body with a second aperture formed therein for receiving the conduit and a second identifying feature that matches the first identifying feature. The first tag is attached to the conduit adjacent one end, the second tag is attached to the conduit adjacent another end, and the ends are identified as ends of the same conduit by the matching first and second identifying features.

A self-extinguishing conduit for conveying a gas capable of supporting combustion of the conduit interior from an upstream to a downstream location includes a combustible tubing and a flow occluder operatively associated with the combustible tubing. The flow occluder is actuated by the heat of combustion within the combustible tubing to substantially halt the flow of gas through the combustible tubing. A combustion resistant material defines a select length of the conduit interior and is provided in series with the combustible tubing. The flow occluder is located downstream and proximate the combustion resistant material. A method for extinguishing combustion within a combustible conduit carrying a combustion supporting gas includes halting migration of combustion within the conduit at a select location and occluding the conduit at the select location.
