Health systems around the world are in dire need of ventilators to help treat the most critical COVID-19 patients. These ventilators essentially breathe for a patient when their lungs become too inflamed or full to work by themselves and thus ensure enough oxygen is continuing to circulate around the body as the patient recovers. 全球卫生系统都急需呼吸机来帮助治疗最危急的新冠患者。患者的肺部严重发炎或者充满黏液无法自主呼吸时，主要依靠呼吸机辅助呼吸，从而在病人康复期间确保有足够的氧气持续在体内循环。 Tesla is one of the many companies using their engineering know-how to turn to producing ventilators to be used on the front line, and in a video posted yesterday engineers at the company showed off their progress. 特斯拉是众多利用工程知识转向呼吸机生产的公司之一，呼吸机将供前线使用。在昨天发布的一段视频中，该公司的工程师展示了他们的进展。 In the video, you first see the Tesla prototype ventilator spread out over a table before seeing it fully assembled. 在视频中，你首先看到特斯拉呼吸机的雏形部件散落在桌子上，然后才被完全组装好。 What’s notable about Tesla’s ventilator efforts is that the company is using parts from its Model 3 cars to build the devices. Tesla says it’s doing this because they know the car parts “really well” and know they are reliable and are also already available in volume. |
