Lung point-of-care ultrasound (POCUS) is a critical tool for evaluating patients with dyspnea in the emergency department (ED), including patients with suspected coronavirus disease (COVID)-19. However, given the threat of nosocomial disease spread, the use of ultrasound is no longer risk free.
Here, we review the lung POCUS findings in patients with COVID-19. In doing so we present a scanning protocol for lung POCUS in COVID-19 that maximizes clinical utility and provider safety.
In COVID-19 lung, POCUS findings are predominantly located in the posterior and lateral lung zones bilaterally. A six-zone scanning protocol that prioritizes obtaining images in these locations optimizes provider positioning, and minimizes time spent scanning, which can reduce risk to health care workers performing POCUS.
Lung POCUS can offer valuable clinical data when evaluating patients with COVID-19. Scanning protocols such as that presented here, which target clinical utility and decreased nosocomial disease spread, must be prioritized.
肺部即时超声检查（POCUS）是评估急诊科呼吸困难患者（包括疑似新型冠状病毒病（COVID-19）患者）的重要工具。然而，鉴于医院内疾病传播的威胁，超声的使用不再是无风险的。
本文回顾了 COVID-19 患者的肺部 POCUS 结果。在这样做的过程中，我们提出了一个针对 COVID-19 肺部 POCUS 的扫描方案，该方案最大限度地提高了临床实用性和医护人员的安全性。
在 COVID-19 肺部，POCUS 结果主要位于双侧后外侧肺区。一个六个区域的扫描方案，优先在这些位置获取图像，优化了医护人员的定位，并最大限度地减少了扫描时间，这可以降低对执行 POCUS 的医护人员的风险。
肺部 POCUS 在评估 COVID-19 患者时可以提供有价值的临床数据。必须优先考虑这里提出的扫描方案，这些方案以临床实用性和降低医院内疾病传播为目标。
