Illinois RapidVent Ventilator

A team led by the University of Illinois at Urbana-Champaign’s Grainger College of Engineering and Carle Health has produced a prototype emergency ventilator to help address the expected surge in the need for respiratory care associated with the COVID-19 pandemic. The team focused on designing a device that could help the sickest patients to breathe, by plugging into the oxygen source available in most hospital rooms or into a tank of oxygen. Within one week, the team demonstrated a working prototype. As of April 2, Illinois RapidVent prototypes had run for more than 1.5 million breathing cycles
