- In the COVID-19 crisis, if a worst case scenario is assumed, about 0.006 percent of the population will require critical care with access to ventilators. For a population of 125 Crores, this translates to about 75,000 patients who might need ventilator access.
Key highlights:
- The global supply chain has been severely disrupted due to the crisis, and there are no indications on when it will be restored. A group of Scientists and students in Indian Institute of Science in Bengaluru have developed an indigenous ventilator prototype.
- The team in the Electrical Communication Engineering Department of Indian Institute of Science, led by Associate Professor Gaurab Banerjee has designed the ventilator using materials readily available in India.
- The prototype has mass flow sensors and controllers which accurately tell how much oxygen is flowing and what volume the patient is inhaling in one breath.
- Pneumatics is built around mass produced water filter hardware. The control system is built around open source industrial controller.
