The invention relates to medical technology and, specifically, to methods and apparatuses for an inhalation effect on the human body. A method consists in forming a respiratory mixture on the basis of oxygen and/or air, and feeding same to a patient with the addition of anesthetic vapors and/or of an aerosol of medicinal agents. An apparatus comprises a respiratory-mixture formation device with a gas source, a primary unit with a unit for setting the volume of respiratory mixture fed to a patient, which are connected to a primary unit of an inhalation/exhalation line having diverters for connecting to the atmosphere, and which are integrated into a patient tee-fitting, a control module, and means for automatic adjustment and monitoring. The control module, aided by the means for automatic adjustment and monitoring, sets a mode for feeding the respiratory mixture along a rebreathing or non-rebreathing loop, using artificial ventilation or autonomous breathing. The invention allows for increasing the efficiency and broadening the functional capabilities of an inhalation effect.
