Abstract
An apparatus for providing breathing gas to a patient that includes a base unit to provide a first flow of gas and a second flow of gas and a humidification canister to be coupled to the base unit is described. The humidification canister includes a first gas flow path to receive and humidify the first flow of gas. A delivery tube assembly includes a first lumen configured for fluid communication with the first gas flow path to receive the humidified first flow of gas and a second lumen to receive the second flow of gas. A method of heating and humidifying the first flow of gas and insulating the first flow of gas with the second flow of gas is also described.
