The Changes in End Expiratory Lung Impedence Measured by EIT and End Expiratory Lung Volume Measured by Passive Expiratory in Controlled Mechanical Ventilated Exacerbation COPD Patients
The First Affiliated Hospital of Guangzhou Medical University
The study hypothesizes that the electrical impedence tomography (EIT) measured the changes of end expiratory lung impedence (△EELI） could accurately predict the changes of end expiratory lung volume （△EELV） measured by passive expiratory in controlled mechanical ventilated exacerbation COPD patients. The research intended to conduct a research to explore the relationship between △EELI and △EELV induced by external PEEP changes in ventilated exacerbation COPD patients.
