A gases flow rate sensing system may be configured to operate in at least two different target temperature modes, based upon a measured temperature of the gases flow. In some embodiments, the gases flow sensing system may have a voltage divider containing a thermistor. The gases flow rate may be determined based upon a voltage output indicating an amount of power needed to maintain the thermistor at a target temperature as specified by the target temperature mode, and a measured temperature of the gases flow.

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.
