An anaesthetic machine for connection to a patient's airways has a fan with an inlet and an outlet, a first system of flow paths connected between the fan's outlet and inlet, and a second system of flow paths connected between the fan's outlet and inlet. A fast system with wide variability with respect to operating modes is achieved by arranging a shunt valve at the fan's outlet in order to regulate the amount of gas flowing into the first system of flow paths and the second system of flow paths respectively, and a control unit is provided to control the shunt valve.
