Retention of noble gases in the respiratory gas in the case of a ventilated patient with the aid of membrane separation

摘要

The present invention relates to the preparation of gas mixtures, especially respiratory for patients.Processing according to the invention relates in particular to the use of selective gas separation membranes to the retention of noble gases in the respiratory gas of ventilated patient, wherein the gas separation membrane is integrated in an artificial respiration apparatus, in order to actively acting as a separating device the zuückzuhaltenden noble gases from the remainder of the expiration gas to separate, in that the diaphragm, the noble gases, which is selectively.In this way, it is possible to provide an artificial respiration apparatus, the use of noble gases, in particular xenon, as an anesthetic particularly simply and with as low as possible consumption losses permits.
