At the end of 2019, a novel coronavirus (COVID-19) was identified as the cause of a cluster of pneumonia cases, with high needs of mechanical ventilation in critically ill patients. It is still unclear whether different types of COVID-19 pneumonia require different ventilator strategies. With electrical impedance tomography (EIT) we evaluated, in real time and bedside, the distribution of ventilation in the different pulmonary regions before, during, and after pronation in COVID-19 respiratory failure. We present a brief literature review of EIT in non-COVID-19 patients and a report of 2 COVID-19 patients: one that did not respond well and another one that improved during and after pronation. EIT might be a useful tool to decide whether prone positioning should or should not be used in COVID-19 pneumonia.
2019年底，一种新型冠状病毒（COVID-19）被确定为一组肺炎病例的病因，重症患者对机械通气的需求很高。目前尚不清楚不同类型的COVID-19肺炎是否需要不同的通气策略。我们利用电阻抗断层成像（EIT）技术，在床边实时评估了COVID-19呼吸衰竭患者俯卧位前后不同肺区域的通气分布情况。我们简要回顾了EIT在非COVID-19患者中的应用文献，并报告了2例COVID-19患者的情况：1例效果不佳，另1例在俯卧位期间及之后病情有所改善。EIT可能是一种有用的工具，可用于决定COVID-19肺炎患者是否应采用俯卧位。
