Device and method for determining regional compliance of lungs

The invention relates to a device and method to determine a value indicative of a respective regional compliance of lungs of a patient (P) in a plurality of different regions of the lungs. An airway pressure sensor (3) measures a value indicative of the pressure (Paw), which is variable over time, at the airway of the patient (P). A difference between the end-inspiratory transpulmonary pressure and the end-expiratory transpulmonary pressure is determined. An EIT measuring device (17) measures by electrical impedance tomography (EIT) a change in volume of a lung region. The difference between the end-inspiratory volume and the end-expiratory volume of the lung region is determined with the use of signals of the EIT measuring device (17). A quotient of the volume difference for the region in question and the pressure difference present at the lungs is calculated as the value indicative of the regional compliance of the lung region. 本发明涉及用于确定患者（P）的肺在所述肺的多个不同的区域中的各自区域性延展性的量度的装置和方法。气道压力传感器（3）测量所述患者（P）的气道处的时间可变压力（P
