Explanation:

The Railways’ Rail Coach Factory (RCF) in Kapurthala has become the first PSU to came out with a prototype ventilator that has an original design and will cost a fraction of what regular ventilators cost. The prototype named Jeevan will now go for final testing at the Indian Council of Medical Research (ICMR) before being put to production to aid the country’s fight against COVID-19. The heart of the device is the compressed air container to work the Ambu bag with air without any moving parts like servo motor or piston or link mechanism.
