A heating wire assembly (16) for reducing condensation in a breathing tube (18) delivering humidified gas to a patient for breathing comprises an electrically resistive heating wire (20), a plurality of thermally responsive sensors (4,10) at discrete locations along the heating wire (20), and at least one signal wire (6,8,12) connected to each of the sensors (4,10). The heating wire (20) and the signal wires (6,8,12) are terminated for connection thereto at a common end of the assembly and are bound together to facilitate insertion of the assembly into a breathing tube (18). A method of assembling a wire (20) or wire assembly (16) into a flexible ventilator tube (18) comprises cooling the wire (20) to a predetermined temperature in order to reduce its flexibility and inserting the wire (20) axially into the flexible tube (18). |
