Abstract

See full text

The invention relates to a regenerative absorber device (20) for the removal of CO.sub.2 from expiration gases during anesthesia. The device comprises a container (38) having an inlet (39) for said expiration gases, and an outlet (41) for output gases, the CO.sub.2 content of which having been substantially removed therefrom. The device is provided with an ion exchanger (42) having the capability to absorb CO.sub.2, disposed in said container (38) such that the gases flow through said ion exchanger from said inlet (39) to said outlet (41). A novel method of anesthesia comprises use of a CO.sub.2 absorber device according to the invention.
