The invention is directed to a method for simulating and demonstrating the gas exchange during ventilation wherein the breathing gas is influenced with respect to its constituents by changing the portion of at least one breathing gas component metered to the carrier gas. The method permits simulation of physiological functions occurring during anesthesia such as the uptake and release of anesthetic agents. For this purpose, an anesthetic agent is admixed to the breathing gas and this anesthetic gas mixture is conducted through a reservoir filled with organic oil to simulate the anesthetic agent uptake and release by the human or animal body.

A method for demonstrating and simulating the exchange of gases during mandatory or assisted ventilation wherein breathing gas passes through a breathing circuit and wherein a breathing gas mixture including oxygen is prepared in a gas supply unit for metering the same into the breathing circuit, the method comprising the steps of: metering anesthetic agent into said breathing gas mixture; passing the breathing gas mixture through reservoir means filled with organic oil simulating a body which is being ventilated whereby portions of the anesthetic agent are dissolved in the oil in said reservoir means; measuring the quantity of anesthetic agent in said breathing gas mixture after the latter has passed through said reservoir means; and, regulating the quantity of anesthetic agent added to said breathing gas mixture in correspondence to the amount of said anesthetic agent dissolved in said oil.
