Abstract: At present,the strategy of setting the optimal positive end-expiratory pressure(PEEP)for mechani-cal ventilation still needs further clinical exploration.Electrical impedance tomography(EIT)is a newly devel-oped technology at the end of the 20th century.It can monitor pulmonary ventilation in real time,so is exten-sively 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 perfu-sion and other information published in recent years,analyzes the basic and clinical research information relat-ed to PEEP effect and its application in individualized PEEP setting.
