Another report on UTMB’s Chris Zahner and Aisen Chacin’s ventilator designed out of easy to find parts. Their device is a simple air pump that uses ordinary blood pressure cuffs, car valves sold by auto parts stores and items found in most hospitals supply closets. “We hope doctors in the U.S. never have to use them, but in an emergency, they should do the trick,” Chacin said. See a video of their emergency pressure cuff ventilator on YouTube.
