<P>PROBLEM TO BE SOLVED: To provide a humidification system providing an option useful in the general public, or at least the general public or the industrial world. <P>SOLUTION: The humidification system includes: a fan 3 driven by a variable speed electric motor for providing a gas flow; humidification means 4, 5 humidifying the gas; a flow rate measuring means 7 for determining a gas flow rate; a humidity sensing means 15 for measuring gas humidity; a first temperature sensing means 12 for measuring temperature of air outside the humidifying system; and a transportation pathway means 6 with an heating means 21 for transporting the humidified gas to the patient; and a control means. The control means includes stored instructions to: (i) determine input power of a transportation pathway heating means based on at least air temperature measured by the first temperature sensing means and the gas flow rate measured by the flow measuring means; and (ii) determine input power of a humidification means based on at least the flow rate of the gas measured by the flow rate measuring means and the humidity of the gas measured by the humidity sensing means to achieve the desired humidity, flow rate, and temperature of the gas to be supplied to the patient. <P>COPYRIGHT: (C)2010,JPO&INPIT |
