摘要	肺可复张性评估在急性呼吸窘迫综合征（ARDS）患者的个体化通气治疗中具有举足轻重的地位。电阻抗断层成像（EIT）作为一项无创且能实时监测的床旁技术，通过对肺组织阻抗变化的监测，可提供复张/过度膨胀权衡比（R/D Ratio）、呼气末肺阻抗（EELI）等关键量化指标，从而实现对肺复张过程的动态可视化呈现。EIT能够精确评估肺可复张性，鉴别高复张表型与低复张表型，并为最佳呼气末正压（PEEP）的个体化滴定提供指导，在复张肺泡与避免肺过度膨胀之间达成最佳平衡。尽管EIT存在空间分辨率有限等局限，但其凭借独特优势，显著提高了肺保护性通气的精准度，具备广阔的临床应用前景。
Abstract	The assessment of lung recruitability plays a critical role in the individualized ventilation management of patients with acute respiratory distress syndrome (ARDS). As a non-invasive and real-time bedside monitoring technique, electrical impedance tomography (EIT) can detect changes in lung tissue impedance, providing key quantitative indicators such as the recruitment-to-overdistension ratio (R/D Ratio) and end-expiratory lung impedance (EELI). This allows for dynamic and visual representation of the lung recruitment process. EIT enables precise evaluation of lung recruitability, distinguishes between high- and low-recruitability phenotypes, and offers guidance for the individualized titration of optimal positive end-expiratory pressure (PEEP), thereby achieving the best balance between alveolar recruitment and avoidance of lung overdistension. Despite limitations such as limited spatial resolution, EIT, with its unique advantages, significantly enhances the precision of lung-protective ventilation and holds broad prospects for clinical application.
