Abstract

System comprises a circuit connectable to the patient for recirculation of exhaled air, an inlet for fresh gas and an absorber to remove CO2. The absorber comprises two units (111, 112) connected in series so that the downstream unit can continue operating after the upstream unit is spend and the absorber is replaced only after both units are spent. Pref. the absorber is replaced when the downstream unit is partially spent and this is moved to the upstream position while a new unit is connected in the downstream position. Pref. either or both units can be bypassed via a valve and conduit (117) arrangement during replacement of one or both units.
