[Research progress of weaning from mechanical ventilation guided by electrical impedance tomography].

Weaning failure from mechanical ventilation is an important clinical problem, the traditional methods of assessing whether patients can be weaned from mechanical ventilation or not cannot meet the clinical needs. Finding more effective weaning indicators to determine the optimal timing of weaning has important clinical value for improving the outcome of weaning and reducing the mortality of patients. As a new method of assessing respiratory function of patients, electrical impedance tomography (EIT) is gradually applied to the clinic, and its guided assessment of respiratory function may open a new way for directing successful weaning. This article reviews the progress of EIT in ventilation weaning, in order to provide a new judgment method and theoretical basis for the successful weaning.
