Transforming bystanders into first responders. It's a critical need in mass shootings, like the one in El Paso, Texas.

Stephen Flaherty, trauma medical director, Del Sol, "The care begins at the site by family friends, family members, bystanders, many of whom have no medical training at all."

Emergency management officials are working to educate everyday people. Expanding the "Stop the Bleed" campaign to all 50 states.

Launched after the Sandy Hook Elementary shooting, it trains how to treat hemorrhaging- one of the primary causes of death in trauma care.

Angela Clarkson is a registered nurse and trauma injury prevention coordinator for Novant Health Presbyterian Medical Center in Charlotte, NC, "We get stories every day of bystanders rendering care and significantly impacting being able to save limbs, being able to save lives."

She runs classes in North Carolina. "Five simple steps. I tell people if you forget the steps, count your fingers."

  • Make sure the scene is safe
  • Call 911
  • Determine the origin of the bleeding
  • Then, compress the wound
  • Either packing it and applying pressure
  • Or using a tourniquet

They can be found in a bleeding control kit, increasingly found in public places or, improvised, using clothing like a scarf.

Techniques useful, Clarkson says, not just in shootings but also other emergencies like car and industrial accidents. Where bleeding is severe and time is of the essence.

Clarkson says it can take as little as five minutes for a person to bleed to death.
