DEVICE FOR DETERMINING THE REGIONAL DISTRIBUTION OF A PARAMETER FOR LUNG PERFUSION

摘要

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).
