简要总结
The purpose of this study is to determine whether the Enlight 2100 electrical impedance tomography (EIT) belt can optimize positive end-expiratory pressure (PEEP) during surgery better than standard anesthesia machines.
详细描述
Positive end-expiratory pressure (PEEP) is a measure taken intraoperatively to manage breathing during surgery. The Enlight 2100 is a device that uses electrical impedance tomography (EIT) to measure PEEP and provide a live image of the lungs while a patient is mechanically ventilated. In this study, the investigators will use the Enlight 2100 EIT belt to measure PEEP intraoperatively in order to better optimize PEEP settings for difficult cases.
