Abstract

An apparatus for supplying respiratory gas to a patient has a first variable volume chamber or bellows (1) connected to a respiratory gas circuit (A) which supplies gas via a facepiece to a patient (15). A respiratory gas (pref. a mixture of O2 and N2O which may contain additional anaesthetic from a vaporiser (22)), is supplied from a respiratory gas preparation device (B). A pneumatic control device (C) has a control unit (3, 9), for controlling the pressure in an inner housing (11) which houses the bellows (1), and which controls the supply of respiratory gas from the bellows (1) to the patient (15). A second, manually operable variable volume chamber (24) can be connected to the respiratory gas circuit (A) instead of the first chamber so that respiration can be effected manually. The bellows (1) are interchangeable so that a bellows having a volume corresponding to the volume of the patient's lungs can be selected. <IMAGE>
