A ventilator for intensified breathing that includes a single safety valve arranged in the gas mixture and inhalation conduit assembly. The single safety valve includes a restrictor valve for overpressure in the breathing system, a valve that allows breathing from the atmosphere, and a directional valve for inhalation. The safety valve is arranged and controlled by an electronic control system of the ventilator.

[ We claim:] [1.] A ventilator for intensified breathing, said ventilator comprisingat least one compressed gas interface for inhalation gas,an inhalation conduit connected to the compressed gas interface for the inhalation of said gas,pressure measuring elements for inhalation gas, said elements being arranged in connection with the inhalation conduit or a space having a flow connection thereto; a restrictor valve for an over-pressure in the inhalation conduit; a valve arranged in the inhalation conduit, said valve allowing breathing only from the atmosphere through the inhalation conduit; and a directional valve for inhalation, arranged in the inhalation conduit,an exhalation conduit for exhalation gas, including an exhalation valve and a directional valve for exhalation, anda control system, which controls the over-pressure restrictor valve on the basis of the pressure measurement of the inhalation gas,whereby the over-pressure restrictor valve and the valve that makes breathing from the atmosphere possible are combined to provide a safety valve, which is arranged to be controlled by said control system and which comprises a closing element; means at least for opening the closing element; and a connection to the atmosphere, said connection being possible to open and close by said closing element,characterized in that the closing element is arranged in the safety valve in such a way that it remains in a closed position at least partly by the impact of gravity, whereby said safety valve also provides a directional valve for inhalation, which closes during exhalation the connection to the atmosphere.
