PCT No. PCT/GB86/00206 Sec. 371 Date Feb. 11, 1987 Sec. 102(e) Date Feb. 11, 1987 PCT Filed Apr. 11, 1986 PCT Pub. No. WO86/05992 PCT Pub. Date Oct. 23, 1986.An apparatus for controlling the flow of gas to and from a patient in an anaesthesia system has first and second flow passages arranged in parallel between the patient and a reservoir bag. Selector valves allow multiple anaesthesia configurations involving no rebreathing or considerable rebreathing. A selector valve can be operated to connect the reservoir bag to either or both flow passages. A one way valve in the first passage, which communicates with a gas supply inlet, can be operated to prevent the back flow of gas from the patient into the passage. A one way valve in the second passage can selectively prevent the flow of gas in the second passage to the patient. The second passage has a selectively bypassable carbon dioxide absorbing fitter and a spill valve. The apparatus allows reconfiguration without disconnecting and reconnecting hoses.
