A remarkable and enlightening incident occurred recently in the Canadian city of Saskatoon. Qian and Grayson Wu, who were 10 and 7, did chest compressions and artificial breathing on their grandmother, who was 62 years old.

They didn’t realize it was a cardiac arrest at the time, but they were well aware that they needed to act swiftly. Here’s how it went down. Keanu Wu, a Canadian child, turned ten years old in June of this year. There was one unusual present among the several that the child got that day.

Kian and his younger brother, Grayson, 7, have always been curious about how people are resuscitated in the event of a cardiac arrest. And their mother, Lee, a nurse at one of Saskatoon’s hospitals, eventually decided to demonstrate this technique to them.

Kian and Grayson decided to pay another visit to their loving grandma, 62-year-old Patty Chatterson, on this day. They initially enjoyed lunch together at a café, then went about the city before returning home in the evening.

After a lovely supper, the whole family sat on the couch in front of the television. Grayson became hungry after a time and decided to ask Patty for something to eat. He looked at her and nearly yelled in terror. Grannie sat with her head flung back, not breathing normally. Her throat made an unusual sound.

The youngsters instantly noticed their grandma had passed out and started calling their mother. However, the phone number did not respond. Kian then proceeded to massage her grandmother’s heart, recalling what their mom had instructed them. Grayson then dialed 911 and, after explaining what had occurred, dictated his grandmother’s address.

The lads placed Grandma on the floor on the recommendation of the emergency dispatcher. Grayson started artificial respiration for her, as Kian performed chest compressions. And he did so with such passion that he cracked many of his grandmother’s ribs in the process. Patty Chatterson started to thank the physicians after regaining consciousness on the fourth day. And she was taken aback when she was informed that she should thank her grandkids first.
