ABSTRACT:
Tubing circuits systems for delivering humidified respiratory gas to a human or an animal are disclosed. The circuit systems include an inspiratory tubing segment and an expiratory tubing segment joined by a manifold assembly. The inspiratory tubing segment is coupled to a humidifier while the expiratory system is coupled to a conventional ventilator. A single heating element is positioned in both the inspiratory and expiratory tubing segment elements. Temperature sensing elements are located at or near the outlet of the inspiratory tubing segment and at or near the inlet of the inspiratory tubing segment. Preferably, portions of all of the single heating element, and the temperature sensors are held by a single connector. The system is very effective in use, safe and easy to use, and provides a convenient, straight forward and reliable system useful in monitoring and controlling the temperature of respiratory gases being delivered to a patient.
