Abstract
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.
