Carbon dioxide is commonly used as an insufflation gas for minimal invasive surgery to enlarge and stabilize body cavities to provide better visibility of the surgical area. Carbon Dioxide can also be used for Cryotherapy, where temperatures of -76° C, can be achieved. Using this technique body cells are destroyed by the process of crystallisation. This may include the removal of wart, moles and skin tags. It can also be used for respiratory stimulation during and after anaesthesia .
