Abstract
A respiratory humidification system humidifies a flow of respiratory gases supplied to a user. The system can include a main housing that receives a humidification chamber, a heating plate included in the main housing and positioned to contact the humidified chamber and transfer heat to the humidifier chamber, and a heating element that provides heat to the heating plate. The heating element can include a temperature sensor disposed in a central region of the heating element. Disposing the temperature sensor in the central region can reduce a likelihood that conductors of the heating element will cause an incorrect temperature measurement by the temperature sensor.
