Abstract
A humidified medical gas supply apparatus to supply gas such as carbon dioxide for laparoscopic surgery includes a gas supply, a supply controller, and a gas supply tube which has a humidification chamber mounted into it. The chamber has a dampened gas-pervious medium and an electrical heating element. The electrical element may extend along the gas supply tube and be wound around the medium within the chamber. A control controls an electrical supply to the electrical heating element to vary the electrical supply dependent upon a gas flow rate in the supply tube.
