A method and arrangement in connection with the ventilation of a patient, wherein the lungs of the patient are ventilated mechanically by means of a ventilator or manually by means of a reservoir bag as the patient's own respiratory activity is insufficient or totally prevented. In order to eliminate a faulty connection, the behaviour of the pressure or the flow in the patient circuit, in the circuit associated with the ventilator or in the circuit associated with the reservoir bag is monitored in connection with ventilation and the obtained information is compared with the desired operation.

Method and arrangement for identifying an existing connection in

An arrangement in connection with a ventilator that comprises a control unit, a bellows unit and a patient circuit, whereby the bellows unit is arranged to separate the control unit from the patient circuit and the control unit is arranged to implement control parameters characterizing lung ventilation. In order to eliminate human error, the arrangement is provided with an identification device that is arranged to identify the bellows unit to be used and to give notification on said bellows unit.
