  • Patent number: 10357624
    Abstract: The invention comprises a ventilation apparatus and method for operating a ventilator of a ventilator apparatus, wherein in the method at least one duration ratio factor is set in a computing system of the ventilator apparatus; at least one minute volume, at least one functional dead space volume and at least one time constant are determined; a respiration frequency is computed, based on a previously defined lung model, depending on said determined parameters, where said computed respiration frequency is optimized on at least one minimum of a delivered parameter, which is induced to a patient using said ventilator; an inspiratory time and an expiratory time are determined based on said computed respiration frequency and said duration ratio factor; at least one tidal volume based on said previously computed respiration frequency and said determined minute volume is computed; and a delivered respiratory parameter of the ventilator is closed loop controlled.
