carbon dioxide snow


carbon dioxide snow
solid carbon dioxide, formed by rapid evaporation of liquid carbon dioxide; it gives a temperature of about −79°C (−110°F). It has been used in cryotherapy to freeze the skin and produce local anesthesia with arrest of blood flow. In the form of carbon dioxide slush, it is used as an escharotic to destroy skin lesions such as warts or moles and as a peeling agent for chemabrasion.
