DEVICE: Oxygen Accessory (00848530106034)

A reduction valve designed to be attached through a gastight connector (e.g., a pin-index or bull-nosed screw thread connection) to the valve stem of a medical gas (e.g., carbon dioxide, oxygen, nitrous oxide, gas mixture) distribution line to reduce high, variable gas pressure to a lower, constant working pressure (excludes procedure-dedicated valves). It will have a safety relief valve to avoid excessive pressure due to increased ambient temperatures, and it may have associated devices (e.g., a manometer, flowmeter) to display the available gas reserve of a gas cylinder, the working pressure, and/or the flow rate.
