Nowhere is this crisis more deeply felt than by the essential workers on the front lines. Dr. Richard Levitan, an airway specialist who has practiced emergency medicine for over 30 years, is well aware of the urgency of their work. When the virus began to overwhelm New York City at the end of March, he rushed from his home in New Hampshire to volunteer at Bellevue Hospital, where he trained. Dr. Levitan recently wrote an op-ed in the New York Times detailing what he's learned from treating COVID-19 patients at Bellevue. He also has co-founded a charitable organization, Prone2Help, which provides healthcare workers with free cushions, since doctors have found placing coronavirus patients on their stomach--called prone positioning--helps increase the amount of oxygen getting to their lungs. Dr. Levitan joins Hari Sreenivasan to discuss his work.
