A dozen Boston area anesthesiology residents launched an eight-week hackathon hosted on GrabCAD.com to design a rapidly deployable, minimum viable mechanical ventilator for patients with COVID-19-related ventilator-dependent lung injury. The CoVent-19 Challenge was open to teams and individuals anywhere, and finalists worked directly with Stratasys 3D printing experts and the CoVent-19 Challenge team to turn their designs into prototypes for testing.
