Abstract
A system for humidifying respiratory gases has a humidification apparatus, a humidification chamber, a heating apparatus and a sensor. The sensor is configured to determine a characteristic of the gases flow and communicate this to a controller which controls the power supplied to the heating apparatus with respect to information regarding the characteristic of the gases flow. A structure partially encloses the humidification chamber and allows energy loss through a wall of the humidification chamber. The humidification chamber may have features to promote heat loss through the wall of the chamber.
