Abstract
A respiratory humidification system that controls the humidity of the outlet gases using an enthalpy based calculation is disclosed herein. The respiratory humidification system includes a controller that can receive data from one or more of an enthalpy sensor, a flow sensor and a temperature sensor. The controller can also receive information relating to the outlet gas enthalpy, which can be calculated from the desired output temperature and humidity. A level of power to be provided to the heating system to achieve the desired output temperature and humidity can be calculated using data from the enthalpy sensor, flow sensor, and temperature sensor, as well as the calculated outlet gas enthalpy.
