Ventilator SOS, a project co-led by mechanical engineering professor Grace O'Connell, is seeking donations of unwanted CPAP and BiPAP machines from people who may have used them for sleep apnea. They are converting the devices into much-needed ventilators for COVID-19 patients. "Tens of thousands of COVID-19 patients in this country and around the world will need respiratory support in the coming weeks and months," Professor O'Connell says. "We believe that using sleep apnea machines is a viable solution for non-ICU patients. This way, higher-grade ventilators can be reserved for patients with more advanced stages of respiratory disease." For more on the project, see this story at Berkeley Engineering.
