摘要
急性呼吸窘迫综合征(ARDS)是临床常见的急危重症,以弥漫性肺间质、肺泡损伤和肺血管通透性增加为特征。CT可用于对ARDS影像学特征、严重程度的评估和预测,但需要转运患者到CT室且仅为静态检查。电阻抗断层扫描(EIT)是近年来在临床应用日益广泛的监测工具,可实现床边连续实时肺通气分布的评估,在优化危重病患者的机械通气参数方面有较高的临床价值。本文介绍EIT基本原理及如何更好地使用EIT技术指导ARDS患者的机械通气治疗。
Acute respiratory distress syndrome(ARDS)is a common and critical clinical condition characterized by diffuse damage to the lung interstitium,alveoli,and increased permeability of pulmonary blood vessels.CT can be used to assess the imaging features,severity,and prediction of ARDS,but it requires patient transportation to the CT room and is only a static examination.Electrical impedance tomography(EIT)is an increasingly widely used monitoring tool in clinical applications in recent years.It enables continuous real-time assessment of lung ventilation distribution at the bedside and has high clinical value in optimizing mechanical ventilation parameters for critically ill patients.This article introduces the basic principles of EIT and how to better utilize EIT technology to guide mechanical ventilation treatment for ARDS patients.
