Electrical Impedance Tomography-Based Prognostic Model for ARDS

Electrical Impedance Tomography-Based Prognostic Model for ARDS: A Multicenter, Prospective, Observational Study

This multicenter, prospective, observational study aims to develop and validate an EIT-based prognostic model for ARDS. By focusing on the pathophysiological characteristics of ARDS and the causes of ventilator-induced lung injury, the investigators intend to establish a prognostic model that reveals lung injury and heterogeneity, enabling risk stratification and guiding individualized treatment.
