Since people began getting sick from COVID-19, there’s been concern about having enough medical supplies of all kinds, including ventilators for very ill patients. While no one wants to be in a position where we need a ventilator, many of us don't know the risks that come with being placed on a breathing machine. And as we learn more about how to treat the coronavirus, some preliminary evidence suggests that in some patients ventilators have done more harm than good. Dr. Reuben Strayer has seen this phenomenon up close. He’s an emergency physician and associate medical director at Maimonides Medical Center in Brooklyn, New York, where COVID-19 has taken hold. He himself has COVID-19, and as an expert on managing critically ill patients with airway and breathing problems, he is the perfect expert to answer the question "What do I need to know about ventilators in light of COVID-19?"
