On the morning of August 3, 2020, three hot air balloons got caught in a downdraft in Jackson Hole, Wyoming and crashed. More than 16 people were injured and scattered across a grassy field, desperate for EMS to arrive. Firefighter Paramedic Kevin Grange was one of the first responders on-scene and, in this informative and entertaining lecture, he details the lessons learned from that chaotic incident and offers up new, evidenced-based science behind Mass Casualty Incidents (MCI) that will change the way you think and act during a large-scale event. Grange will review new guidelines on patient triage, treatment and transport during a MCI, the revised trauma “diamond of death," the command and human performance lessons he learned during the chaotic incident and discuss the concepts behind setting up a “casualty collection point.” Whether you work as a wilderness physician, paramedic, in search and rescue or simply find yourself as a spectator at “soft target” like a music concert, ski area or national park where a MCI occurs, the result will be an educational and engaging presentation that is, unfortunately, applicable to everyone in this day and age.
