PROBLEM TO BE SOLVED: To provide a humidification system capable of controlling temperature, humidity and flow rate. In some embodiments, a humidification system includes a heater base having a heating plate, a humidification chamber, and a circuit. The circuit may include various conduits including an inspiratory conduit 120, an expiratory conduit 122, a Y-piece 124, a patient conduit 126, and/or a drying conduit 132. In use, the chamber contains a quantity of liquid. The heater base heats the heating plate, which in turn heats the liquid to a temperature such that at least some of the liquid becomes vapor, thereby humidifying the gas in the chamber. The gas is delivered to the patient via the inspiratory conduit. Various features help control the system and ensure that the patient receives the gas with the desired conditions.
