ICU可视化动态评估心肺功能新技术:电阻抗断层成像

A new technology for visual dynamic assessment of cardiopulmonary function in ICU:electrical impedance tomography

电阻抗断层成像(EIT)是一种无辐射、可视化的床旁无创、连续、动态监测的功能成像技术,不仅可实时显示肺区域性通气状态,还可进行肺灌注的评估。因此,EIT能帮助医师在直视状态下从生理学角度识别动态心肺功能,进而制定个体化呼吸支持策略。本文探讨ICU不同场景下EIT的研究成果为危重症患者个体化呼吸支持策略及临床救治提供证据支持。

Electrical impedance tomography(EIT)is a radiationless,visual,bedside,non-invasive,continuous,an dynamic monitoring functional imaging technique,which not only visualizes the regional pulmonary ventilation status in real time,but also assesses pulmonary perfusion.It assists in identifying dynamic cardiopulmonary function from a physiological perspective under direct vision and thus develop individualized respiratory support strategies.This review summarizes research results about EIT in different ICU scenarios,aiming to provide evidence to support individualized respiratory support strategies and clinical care for critically ill patients.
