A respirator circuit comprises a breathing tube, such as an endotracheal tube, having a proximal end, a distal end, and a lumen extending between the proximal and distal ends. The lumen defines at least a portion of the respirator circuit. A ventilator tube is in fluid communication with the proximal end of the breathing tube end and defines a portion of the respirator circuit. One or more light sources capable of emitting ultraviolet radiation irradiates at least a portion of the respirator circuit, thereby sterilizing the respiratory circuit.
