Gas, laughing (health)


Nitrous oxide, a gas capable of causing general anesthesia. Today nitrous oxide is sometimes given in the company of other anesthetic agents but is no longer used as the sole anesthetic agent because the concentration of nitrous oxide needed to produce anesthesia is close to the concentration that seriously lowers the blood oxygen level and creates a hazardous state of hypoxia.
