Abstract
A method and an arrangement for processing respiratory gas of an intubated patient, wherein the level of humidity of the inhalation gas is increased, if necessary, before the gas is supplied to the patient. To provide accurate and correctly timed humidification, the patient's respiratory volume is measured, the amount of water discharged from the patient is determined on the basis of the measured respiratory volume, and a desired amount of water, dependent on the amount of water discharged from the patient, is supplied to the patient's respiratory tract during the next respiratory phase(s).
