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。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。
health systems around the world are in
1 need of ventilators to help treat the most critical covid-19 patients. these ventilators
2 breathe for a patient when their lungs become too
3 or full to work by themselves and thus ensure enough oxygen is continuing to circulate around the body as the patient recovers.
tesla is one of the many companies using their engineering
4 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.
in the video, you first see the tesla prototype ventilator spread out over a table before seeing it
5 assembled.
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.
model 3 parts used in the tesla ventilators include a mixing
6 and vehicle controllers and several
7 of its model 3 infotainment system, including the touchscreen and infotainment computer.
