Abstract
In a ventilator system and a method for controlling the ventilator system, a hand ventilator is connectable to a patient to impose a manually generated breathing pattern on the patient. A measurement unit is arranged by the hand ventilator to measure at least one of the parameters pressure and flow of the manually generated breathing pattern. The measured parameters are supplied to a memory unit in a regulatory unit, which operates a control unit so as to regulate a valve unit for imposing a mechanically generated breathing pattern, corresponding to the manually generated breathing pattern, on the patient. The measured parameters can be re-scaled in a calculation unit before the control unit controls the valve unit.
