An improved medical conduit including a heating element for controlling the temperature and humidity of a gas to be delivered to a recipient patient is disclosed. A flexible ribbon spanning the width of a flexible tubing and extending generally the length of the tubing is provided, where the flexible ribbon carries a heatin g element therein. The heating element, preferably an electrically conductive wire or plurality of wires, is connected to a power supply in order to heat the flow of gas traveling within the tube.
