Hero 8-year-old boy saved his baby sister’s life thanks to CPR skills he learned from a Nickelodeon TV show.

Jackson Dempsey, 8, became a real superhero after he saved his little sister’s life. The Heights-Terrace Elementary second-grader managed to perform much-needed CPR on his younger sibling – 20-month-old Leila.

As per 9GAG, Jackson learned while watching WWF star John Cena on the Nickelodeon TV show ‘The Substitutes.’ Talking to CBS affiliate WYOU, the heroic brother said:

“It made me feel scared because I thought she was going to die but then this thing came into my mind. I told my dad to pull over and I started to pat her back and it got out.”

He later revealed exactly where he got the life-saving skill from:

“It’s called The Substitutes on Nickelodeon, and in the very first episode, John Cena was on it, and in the last part, he showed how to save someone when they’re choking.”

Jackson’s father said his son was always a “good big brother.”

The brave 8-year-old’s dad Matt Dempsey was not surprised by his son’s benevolent deed. He explained:

“He amazes us every day, you know—some of the things he says and does, and his actions. We’re simply blessed to have the child that he is, the things that he does for his family, his friends, for his little sister. He’s a good big brother.”

Matt said he was incredibly grateful for his son’s quick reaction. He continued:

“If I was by myself and Jaxson wasn’t with me, and I stopped and gave her a chicken nugget, I couldn’t hear her because she was choking. She wasn’t coughing; she wasn’t panicking. She just had no air going through; she wasn’t breathing.

Thank God Jaxson was there because, without him, I don’t know if Lelia would be here.”

This is yet another proof of how tremendously important CPR education is.

Earlier this week, we told you about a 16-year-old schoolgirl who saved her best friend’s life thanks to the CPR training she had completed the previous day. Moments after a car crash, Torri’ell Norwood of Lakewood High School in St. Petersburg, Florida, saved her friend A’zarria’s life after performing CPR she learned only a day before the accident.
