Abstract
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.
