Abstract
There is suggested a system for automated adjustment of a pressure set by a respiration device, in particular a positive end-expiratory pressure and/or a maximum airway pressure, comprising: an arrangement for electrical impedance tomography for detecting an electrical impedance distribution along at least a two-dimensional cross-section through the human thorax at least at the end of an inspiration phase and at the end of an associated expiration phase; a device for dividing the detected electrical impedance distribution at the end of the inspiration phase and at the end of the expiration phase into a plurality of EIT pixels and for determining a value of the electrical impedance at the end of the inspiration phase and at the end of the expiration phase, as associated with a respective EIT pixel; and a device for automated adjustment of the pressure set by the respiration device on the basis of a comparison (i) of a deviation between the value of the electrical impedance at the end of the inspiration phase associated with an individual EIT pixel and the value of the electrical impedance at the end of the expiration phase associated with the respective individual EIT pixel (ii) with a deviation between the value of the electrical impedance at the end of the inspiration phase and the value of the electrical impedance at the end of the expiration phase, as determined on the basis of the entirety of EIT pixels.
