  • Patent number: 12274827
    Abstract: A method for determining a regional compliance of a lung during spontaneous respiration. In the method, a lung compliance value C.M is determined by triggering an inspiration maneuver and either measuring a compliance of the entire lung or of a surrogate for the compliance of the entire lung. In the method, there further is a capture of an electrical impedance distribution along at least one two-dimensional section through a human thorax by a device for electrical impedance tomography, with a multiplicity of EIT pixels being captured. An end-inspiratory and an end-expiratory electrical impedance are determined for each EIT pixel and an impedance difference is determined for each EIT pixel. The regional compliance is determined for specific EIT pixels, which are assigned to an impedance value range based on a frequency distribution of all EIT pixels.

    Abstract: A method for operating a ventilator for artificial ventilation of a patient, comprising: initial recording of at least one patient-specific physiological parameter, initial setting of at least one technical respiration parameter, and ventilation of the patient based on the technical respiration parameter. The technical respiration parameter corresponds to at least one of respiratory minute volume (VE), tidal volume (VT), respiratory rate (RR), positive end-expiratory pressure (PEEP), or inspiratory oxygen concentration (FiO2) made available by the ventilator. A repeating measurement of the parameter is carried out by the ventilator at time intervals, and an adaptation of the parameter is effected by the ventilator based on said repeating measurement. A ventilator for artificial ventilation of a patient is also proposed.
