摘要：
A respiratory assistance system (1, 100, 200) to provide a user with a stream of humidified and heated gases for therapeutic purposes, comprising； a humidifier unit (5, 12, 21) having an intake orifice (23) and an outlet (9), wherein said humidifier unit (5, 12, 21) is adapted to receive, in use, a flow of gases from a gas source (3, 103, 213) through said intake port (23) and said humidifier unit (5, 12, 21) is further adapted to contain and heat a volume of water in use, passing in use said gas flow through said humidifier unit (5, 12, 21) and being heated and humidified, said humidified and heated gases leaving said humidifier unit (5, 12, 21) through said outlet hole of the humidifier unit (9), and wherein said humidifier unit (5, 12, 21) comprises a humidifier chamber (5) having a heating base, a heating plate (12) adapted to heat the contents of said humidifier chamber (5) by providing thermal energy to said heating base, a t sensor temperature of the heating plate (62) adapted to measure the temperature of said heating plate (12), a temperature sensor of the outlet orifice (63) adapted to measure the temperature of the gases leaving said humidifier unit, a sensor of ambient temperature (60) adapted to measure the temperature of the gases at a point before said gases enter said humidifier unit (5, 12, 21), a flow sensor (61) adapted to measure the actual flow of said current of gases through said system (1, 100, 200), a controller (8) adapted to: receive data from said ambient temperature sensor (60) related to the measured temperature, data from said orifice temperature sensor output (63) related to the measured temperature data from said temperature sensor of the heating plate (62) related to the measured temperature and data from said flow sensor (61) related to said real flow rate, characterized in that the controller (8): determines a target temperature for the gases that leave said humidifier unit through said outlet orifice (9) based on at least the dat
