Ventilators aren't enough for some very sick COVID-19 patients. The Bradykinin Storm could explain why.

Scientists at the Oak Ridge National Laboratory had a eureka moment. They discovered something that helps explain the varied symptoms of COVID-19, and why ventilators don't always help the sickest patients. And it may send the search for treatments in a whole new direction. Dr. Dan Jacobson, Chief Scientist for Computational Systems Biology at Oak Ridge National Laboratory joins KYW In Depth to break down what they found and what it means.
