Basic Life Support in Children

Your neighbour is knocking at the door saying that she had left her 5-year-old daughter playing on the floor. When she got back, the girl was lying on the floor without movement. What will you do?
You will ask her to give a cough.
You will give her 5 back blows.
You will check for a response by shaking her shoulder and asking her loudly: “What has happened to you”?
