It takes less than four minutes for someone to bleed to death.
That's why less the American College of Surgeons started 'Stop the Bleed.'
It's a national program that teaches everyone how to stop life-threatening bleeding until medical help arrives.
So, Shock Trauma held a 'Mini-Med School' teaching about 200 people to stop the bleed.
Something Dr. Habeeba Park calls a necessary life skill.
"iI's tricky thing to ask someone who doesn't have any medical background to look at bleeding, so I hope they feel a little more comfortable if they see bleeding to decide whether or not they think the person's life is in danger and then they can actually feel empowered to do something about it," said Dr. Park.
Shock Trauma has trained nearly 3,000 people since it started the program in 2017.
And the best part, all the classes are free.
