The course aims to turn bystanders into immediate responders who will intervene without waiting for EMS, much like performing CPR for victims of sudden cardiac arrest. While much of the public awareness of Stop the Bleed has come in response to intentional mass-casualty events like Sandy Hook, the effectiveness of immediate responders has been demonstrated in natural disasters and such everyday incidents as motor vehicle collisions and playground accidents. By empowering members of the public to intervene and reduce the number of preventable deaths from trauma, we can increase resilience in the face of tragedy.
