The changes of pulmonary blood flow in non-ventilated lung during one lung ventilation

摘要

Objective A pulmonary artery catheter place- ment is necessary for intrapulmonary shunt fraction evaluation. The purpose of this study was to investigate the feasibility for detecting the changes of regional pulmonary blood flow in non-ventilated lung by transesophageal echocardiography (TEE) during one-lung ventilation (OLV).
