Brothers, age 7 and 10, perform CPR to save grandmother in cardiac arrest |CPR First Aid NJ and NY

It was a Saturday night and seven-year-old Grayson Wu said that he knew something was wrong with his grandma when he asked for a snack and she didn't answer.

"So I looked over and she was, like..." he said.

"Unconscious, on the couch," interjects 10-year-old Kian Wu, rolling his head back and opening his mouth wide to illustrate.

"She looked really dead," adds Grayson. "Spit was going back into her mouth. She was grunting a little."

He makes a gurgling sound.

It was Nov. 10 and the brothers were having a sleepover at their grandma's house in Saskatoon. They'd just watched a movie when 62-year-old Patti Chatterson had a massive heart attack and went into full cardiac arrest.

"It was so scary. I didn't want to let our grandma die," said Grayson.

"We just acted," said Kian.

Grayson and Kian describe the moment they saw their grandmother wasn't breathing.
