carbon dioxide

an odorless, colorless gas, CO2, resulting from oxidation of carbon, formed in the tissues and eliminated by the lungs; used in some pump oxygenators to maintain the carbon dioxide tension in the blood. It is also used in solid form; see carbon dioxide snow and carbon dioxide slush.
carbon dioxide combining power the ability of blood plasma to combine with carbon dioxide; indicative of the alkali reserve and a measure of the acid-base balance of the blood.
carbon dioxide content the amount of carbonic acid and bicarbonate in the blood; reported in millimoles per liter.
carbon dioxide–oxygen therapy administration of a mixture of carbon dioxide and oxygen (commonly 5 per cent CO2 and 95 per cent O2 or 10 per cent CO2 and 90 per cent O2); used for improvement of cerebral blood flow, stimulation of deep breathing, or treatment of singultation (hiccupping). Carbon dioxide acts by stimulating the respiratory center; it also increases heart rate and blood pressure. Therapy is given for 6 minutes or less with a 5 per cent mixture and 2 minutes or less with a 10 per cent mixture. Potential adverse effects include headache, dizziness, dyspnea, nausea, tachycardia and high blood pressure, blurred vision, mental depression, coma, and convulsions.
carbon dioxide slush solid carbon dioxide combined with a solvent such as acetone, and sometimes also alcohol; used as an escharotic to treat skin lesions such as warts and moles and as a peeling agent in chemabrasion.
carbon dioxide snow the solid formed by rapid evaporation of liquid carbon dioxide, giving a temperature of about −79°C (−110°F). It has been used in cryotherapy to freeze the skin, thus producing local anesthesia and arrest of blood flow. See also carbon dioxide slush.

car·bon di·ox·ide snow

solid carbon dioxide used in the treatment of warts, lupus, nevi, and other skin affections, and as a refrigerant.
