12-year-old saves drowning man after learning CPR skills from Stranger Things

A 12-year-old boy has saved his behavioural therapist from drowning after doing vital CPR.

But what's even more incredible about this story is that he learned those lifesaving skills from a very popular Netflix show.

Austen MacMillan from Palm Beach County, Florida, watched as Jason Piquette fell into a pool.

When he noticed the therapist had been underwater for far too long, he sprang into action.

“It was like six to five minutes he was under the water and I was like, 'That's way too long. He can not do that',” Austen recalled to Good Morning America.

The pre-teen jumped into the deep end and pulled Jason to the pool steps.

As the therapist laid there unconscious, the 12-year-old ran outside the home to yell for help.

When no one came, he came back to the pool and started administering CPR.

Austen's dad came home and quickly called 911 just as Jason started regaining consciousness.

"I think I passed out in about 30 seconds and I don't know why," Piquette said.

He added: "I'm just so, like, amazed at how strong he was and how wise he was in that moment. And I always want him to know that he is a hero."

The whole incident was captured on the home recording system and has since gone viral.

When asked how he knew how to do CPR so well, he revealed that he learned it from watching Stranger Things.

There's a scene in the first season where David Harbour's character Hopper has to do CPR on Will Byers in the Upside Down.

The 12-year-old's mother couldn't believe her son was so brave: "I almost felt like I couldn't speak, my whole body like locked up.

"It was definitely a really proud mom moment, he's really brave and courageous."

The family hopes this serves as a reminder for why learning CPR is so important in situations like this.

When you don't have anyone to call for help, it's worth knowing what to do to keep a person's heart pumping.
