Stop the Bleed course

Most skills we learn to be able to use someday. But the skills being taught in the simulations at a "Stop the Bleed" class in Stony Brook, Long Island, nobody wants to have to use, ever. Dr. James Vosswinkel is chief of trauma surgery at Stony Brook University Hospital. His students on this day were not premed. They're school staffers who work with the 6,000-plus children from pre-K to 12th grade in the Three Village Central School District. They all came voluntarily under the cloud of frequent school shootings, knowing we are all vulnerable.
