A respiration humidifier has a metering device (3, 10) and an electrically heated evaporator (4), which is in connection with or can be connected to the metering device (3, 10) on its inlet side (E) and with a respiratory gas channel (5), through which respiratory gas can flow, on its outlet side (A

A respiration humidifier has a metering device (3, 10) and an electrically heated evaporator (4), which is in connection with or can be connected to the metering device (3, 10) on its inlet side (E) and with a respiratory gas channel (5), through which respiratory gas can flow, on its outlet side (A). The metering device (3, 10) feeds the amount of water necessary for humidifying the respiratory gas to a predetermined relative humidity of the respiratory gas at a predetermined respiratory gas temperature to the evaporator (4) per unit of time as a function of the amount of respiratory gas flowing through per unit of time. The evaporator (4) provides water vapor with a temperature above 134.degree. C., which heats the respiratory gas to the predetermined respiratory gas temperature on mixing with the respiratory gas to be humidified.

[ What is claimed is:] [1.] A respiration humidifier for use with a respiratory gas channel flowing respiratory gas, the respiration humidifier comprising:a metering device for feeding water; andan electrically heated evaporator having an inlet and an outlet, said inlet having a connection with said metering device and said outlet being connectable to the respiratory gas channel, said metering device providing a water feed in an amount to control a relative humidity of the respiratory gas at a predetermined respiratory gas temperature to said evaporator per unit of time as a function of an amount of respiratory gas flowing through per unit of time, and said evaporator providing water vapor and controlling a water vapor temperature above 134.degree. C., to heat the respiratory gas and control a temperature of the respiratory gas on mixing of the water vapor with the respiratory gas.
