  • Patent number: 10064568
    Abstract: A device for determining the regional distribution of a parameter for lung perfusion includes an electrical impedance tomography unit with electrodes (E1, . . . EN), which can be placed on the thorax, that are connected to a control and analysis unit (2) and an administering device (4) for the intravenous administration of a conductivity contrast medium. The control and analysis unit (2) is configured to display changes in impedance distribution occurring as a consequence of the administration of conductivity contrast medium as a parameter for lung perfusion in the section plane as a function of time. The administering device (4) has a controllable dispensing device. The control and analysis unit and the dispensing device are connected with one another via a data link (3). A start time and an end time and a quantity of an administered bolus of the conductivity contrast medium are available to the control and analysis unit (2).

  • Patent number: 8105242
    Abstract: A process with a corresponding device for lung ventilation involves recording an image of the lung status with an electric impedance tomography (EIT) system (2) and the total area of ventilated lung areas is determined by a computing unit (4) from all image values, subsequently divided into at least two lung areas and the extent of the homogeneity of the ventilated lung areas is determined by comparison of the impedance changes within these areas. In case of a homogeneity rated as being too low, the respiration pressures are increased step by step by means of the respirator (1) and the respiration pressure at which the greatest possible homogeneity is obtained from subsequently determined status images is determined by means of the EIT system (2).

  • Patent number: 7896814
    Abstract: An electro-impedance tomography (EIT) system (2), with a computing unit (4) and a respirator (1) is described for gentle mechanical lung ventilation especially in case of atelectases. The presence, the extent and/or the spatial distribution of atelectases is detected by the EIT system (2) and sent to the respirator (1) so that the respiration pressure is increased step by step by the respirator (1) until the current image of the lung status corresponds to a first status image of healthy lungs or comes close to it with minimal deviations. The respiration pressure is subsequently reduced again step by step by the respirator (1) until the computing unit (4) detects a reduction of the ventilated lung areas and the respiration pressure is subsequently increased again by means of the respirator (1) to the last value at which no change occurred in the ventilated lung areas.

  • Patent number: 7584752
    Abstract: A device and a process for determining the change in the functional residual capacity (FRC) in a simple manner. Based on a first respiration phase for mechanical respiration, a recruitment maneuver is performed for this during a second respiration phase, and respiration is switched back to mechanical respiration during a third respiration phase. Reference values Uref/1, Uref/3 are formed from the end-expiratory values of the impedance measured signals U during the first respiration phase and the third respiration phase, and the difference ?U (?FRC) between the reference value Uref/3 of the third respiration phase and the reference value Uref/1 of the first respiration phase is an indicator of the change in the functional residual capacity of the lung of the test subject.

  • Publication number: 20070246046
    Abstract: A process and a device is presented with an electro-impedance tomography (EIT) system (2), with a computing unit (4) and with a respirator (1) for gentle mechanical lung ventilation especially in case of atelectases following surgical procedures. A first image of the healthy lungs is first recorded prior to anesthetization by means of the EIT system (2) and the total area and/or the spatial distribution of ventilated lung areas are determined from the image values by means of the computing unit (4). Second or additional status images are recorded after assumed lung damage and the total area and/or the spatial distribution of ventilated lung areas are determined. The total areas and/or the spatial distribution of the ventilated lung areas from the first and second or further status images are compared by means of the computing unit (4) and analyzed for the presence of lung areas that have no or reduced ventilation due to atelectases.
