Research progress on electrical impedance tomography guiding positive end-expiratory pressure setting during mechanical ventilation

Abstract

Abstract: At present, the strategy of setting the optimal positive end-expiratory pressure (PEEP) for mechanical ventilation still needs further clinical exploration. Electrical impedance tomography (EIT) is a newly developed technology at the end of the 20th century. It can monitor pulmonary ventilation in real time, so is extensively important to optimal PEEP setting. This review summarizes the principles of using EIT to guide PEEP setting, monitoring respiratory system compliance, spatial distribution, temporal distribution, local lung perfusion and other information published in recent years, analyzes the basic and clinical research information related to PEEP effect and its application in individualized PEEP setting.

Key words: electrical impedance tomography, mechanical ventilation, positive end-expiratory pressure, ventilator-associated lung injury
