Matthew Callaghan, inventor of the OneBreath portable ventilator. He began developping the device four years ago, after realizing that logistically, since ninety-five percent of the ventilators in the U.S. are already in use at any given time, if many people became ill at once (say due to a flu pandemic), medical professionals would be forced to make some very difficult decisions. Plus, to buy new state-of-the-art models, it would cost hospitals anywhere from three to forty thousand dollars.
The ventilator originates from the Iron Lung which was invented by Philip Drinker and Louis Agassiz Shaw. In 1931, the Iron Lung was improved to become the ventilator by John Haven Emerson.
