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.
