carbon dioxide + oxygen + nitrogen

This is a medical gas mixture composed of carbon dioxide, oxygen, and nitrogen in varying proportions. It is supplied as a compressed gas for respiratory administration by inhalation. The specific formulation may vary but typically contains approximately 5% carbon dioxide, 20% oxygen, and 75% nitrogen per liter. This combination is used under the supervision of healthcare professionals for specialized clinical applications such as respiratory stimulation testing or calibration of medical devices[6][8]. The mechanism involves providing controlled concentrations of these gases to influence respiration and other physiological parameters.
