ABSTRACT:
A humidifier having an ambient temperature sensor for sensing the temperature of the ambient air in the environment in which the humidifier is located. A difference temperature selector is provided to allow a user to select a difference temperature which is the difference in temperature between the sensed ambient temperature and a comfortable and efficient temperature for supply of the humidified gases provided by the humidifier to a patient or user. The humidifier controls the temperature of the humidified gases it provides to the patient to the selected difference temperature above the sensed ambient temperature, so that any change in the sensed ambient temperature results in a corresponding change in the temperature of humidified gases supplied to the patient or user. This construction prevents or minimises the condensation which occurs at low ambient temperatures in the gases supply conduit provided between the humidifier and the patient or user.
