An anaesthetic machine (2), designed for connection to a patient's (4) airways, comprising a fan (6) with an inlet (8) and an outlet (10), a first system of flow paths connected between the fan's (6) outlet (10) and inlet (8) and a second system of flow paths connected between the fan's (6) outlet (10) and inlet (8), is described. A fast system with great variability with respect to operating modes is achieved when a shunt valve (20) is arranged at the fan's (6) outlet (10) in order to regulate the amount of gas flowing into the first system of flow paths (12, 14, 16) and the second system of flow paths (18, 30, 32) respectively, and a control unit (22) is arranged to control the shunt valve (20). <IMAGE> |
