Electrical impedance tomography (EIT) is an emerging imaging modality that can be used to diagnose ventilatory and intrathoracic perfusion mismatches in unstable patients at the bedside. We present a case of a postoperative hypoxic patient in the intensive care unit (ICU) who was too unstable for transport for computed tomography (CT) imaging but was diagnosed and treated for a pulmonary embolism using EIT at the bedside. After the patient clinically improved, CT imaging confirmed the pulmonary embolism diagnosis. EIT is a promising diagnostic tool that may have great utility in ICUs, where it can be safely applied at the bedside.
电阻抗断层成像（EIT）是一种新兴的成像方式，可用于在床边诊断不稳定患者的通气和胸腔内灌注不匹配。我们报告了一例术后低氧血症患者在重症监护病房（ICU）的病例，该患者因不稳定而无法进行计算机断层扫描（CT）成像，但使用 EIT 在床边诊断和治疗了肺栓塞。患者临床症状改善后，CT 成像证实了肺栓塞的诊断。EIT 是一种很有前途的诊断工具，在 ICU 中可能有很大的应用价值，因为它可以安全地在床边应用。
