Devesh Ranjan leads research team at Georgia Tech to create a ventilator
Prof. Devesh Ranjan, who is with Georgia Tech’s George W. Woodruff School of Mechanical Engineering, led a research team at Georgia Tech to create a prototype for a low-cost, portable emergency ventilator that uses electronic sensors and computer control to manage key clinical parameters such as respiration rate, tidal volume (the amount of air moved into and out of the lungs during each cycle), inspiration and expiration ratio, and pressure on the lungs. The ventilator, called Open-AirVentGT, has been designed to address acute respiratory distress syndrome, a complication that causes the lungs of Covid-19 patients to stiffen. The new device endeavors to make breathing more natural by allowing patients to trigger their own breaths instead of relying on a respiration rate pre-set in the device. The World Economic Forum’s Global Lighthouse Network invited him to present his invention at a meeting.
