In an 8,000 sq ft (743 sq m) facility in the western Indian city of Pune, a bunch of young engineers are racing against time to develop a low-cost ventilator that could save thousands of lives if the coronavirus pandemic overwhelms the country's hospitals.These engineers - from some of India's top engineering schools - belong to a barely two-year-old start-up which makes water-less robots that clean solar plants.
India, by most estimates, only has 48,000 ventilators. Nobody quite knows how many of these breathing assistance machines are working. But it is a fair assumption that all those available are being used in intensive care units on existing patients with other diseases, reports BBC.
About one in six people with Covid-19 gets seriously ill, which can include breathing difficulties. The country faces seeing its hospitals hobbled as others around the world have been, with doctors forced to choose who they try to save.
At least two Indian companies make ventilators at present, mostly from imported components. They cost around 150,000 ($1,987; £1,612) rupees each. One of them, AgVa Healthcare, plans to make 20,000 in a month's time. India has also ordered 10,000 from China, but that will meet just a fraction of the potential demand.
The invasive ventilator being developed by the engineers at Nocca Robotics will cost 50,000 rupees ($662). Within five days of beginning work, a group of seven engineers at the start-up have three prototypes of a portable machine ready.
They are being tested on artificial lungs, a prosthetic device that provides oxygen and removes carbon dioxide from the blood. By 7 April, they plan to be ready with machines that can be tested on patients after approvals.
