Abstract：
Electrical impedance tomography (EIT) is a new method of monitoring non-invasive mechanical ventilation, at the bedside and useful in critically ill patients. It allows lung monitoring of ventilation and perfusion, obtaining images that provide information on lung function. It is based on the physical principle of impedanciometry or the body\'s ability to conduct an electrical current. Various studies have shown its usefulness both in adults and in pediatrics in respiratory distress syndrome, pneumonia and atelectasis in addition to pulmonary thromboembolism and pulmonary hypertension by also providing information on pulmonary perfusion, and may be very useful in perioperative medicine; especially in pediatrics avoiding repetitive imaging tests with ionizing radiation.
摘要：
电阻抗断层成像(EIT)是一种新的无创机械通气监测方法,在床边，对危重病人有用。它允许肺部监测通气和灌注，获取提供肺功能信息的图像。它基于阻抗测量法的物理原理或人体传导电流的能力。各种研究表明，它在成人和儿科呼吸窘迫综合征中都很有用，肺炎和肺不张除了肺血栓栓塞和肺动脉高压还提供肺灌注信息，并且可能在围手术期医学中非常有用；特别是在儿科中，避免使用电离辐射进行重复的影像学检查。
