This is the heroic moment a quick-thinking child saves his mother as she chokes on a grape.

CCTV footage begins with the mother sitting at a table, coughing and spluttering after apparently swallowing a fruit in their home in Jinan, China, on January 17.

Three grapes can be seen on the table next to her smartphone.

Her children, a 10-year-old boy and a six-year-old girl, enter the room to check on her. The son quickly puts down his device and hits her on the back to help her cough up the fruit.

When that does not work, he tries to give her something to drink, but she is coughing too much to manage, so he puts the phone down again.

The young boy then gets behind his mum and performs the Heimlich manoeuvre, with the woman eventually coughing up the obstruction.

As she breathes deeply, still shaken from the ordeal, he picks up his smartphone and returns to his game as the video ends.

The Heimlich manoeuvre, also known as abdominal thrusts, is a first-aid technique used to help someone choking due to a foreign object obstructing their airway. It is designed to expel the object by creating pressure in the abdomen.
