Abstract
An improved heated cartridge humidifier for delivering humidified respiratory gases to patients. A humidifier housing includes a gas and water supply and a gas outlet. A humidifier base plate engages a heating element. The base plate includes a central heat conductive portion retained in an outer insulating portion which prevents the lateral dissipation of heat received from the heating element. The baseplate enhances the heat transfer to the water, and therefore, enhances the humidity of the gases.
