摘　　要：急性呼吸窘迫综合征是以急性低氧性呼吸衰竭为特征,胸部影像学显示双侧肺组织浸润渗出,不能完全用心力衰竭或体液超载来解释。目前,CT扫描常用于急性呼吸窘迫综合征的分类和预后,但受限于危重患者转运不便等情况,此项检查无法满足实时监测肺组织通气与灌注的需求。电阻抗断层扫描的出现很好的解决了这一问题。电阻抗断层扫描作为一项新兴的功能性成像技术,能够无创、实时地评估肺部通气和灌注情况,从而协助急性呼吸窘迫综合征诊断、评估危重程度、优化患者机械通气参数以及疗效评估。本文主要对电阻抗成像技术在急性呼吸窘迫综合征患者病情监测中的研究进展进行讨论。Acute respiratory distress syndrome(ARDS)is characterized by acute hypoxemic respiratory failure.The chest imaging shows the bilateral pulmonary infiltration and exudation.These cannot be fully explained by heart failure or fluid overload.Currently,computed tomography(CT)is commonly used for the classification and the prognosis of patients with ARDS.However,due to the inconvenience of transporting critically ill patients,this examination cannot meet the needs of real-time monitoring of ventilation and perfusion of lung tissue.The emergence of electrical impedance tomography(EIT)has solved this problem very well.As an emerging functional imaging technology,EIT can real-time assess the lung ventilation and perfusion non-invasively.Thus,it assists in the diagnosis of ARDS,evaluates the severity of illness,optimizes the mechanical ventilation parameters for patients,and assesses the treatment effectiveness.This article mainly discusses the research progress of EIT technology on monitoring the conditions of ARDS patients.
