Historical information
Francis Percival de Caux invented this endotracheal tube which was devised for use during nitrous oxide/oxygen anaesthesia. Though he wasn't the first to use a two-tube method of anaesthesia, de Caux's invention was particularly effective; in 1930 he reported having given 20,868 nitrous oxide/oxygen anaesthetics in a four year period without a fatality.
Physical description
