1. Check whether he can breathe, cry or cough. If he can still breathe when coughing, tell him to be quiet, and at the same time continue to cough and cough up the food.

Don't pat him on the back, it may stuff the food more tightly. Once the trachea is blocked, he can't breathe. Avoid using heimlich method, which may aggravate airway obstruction and is no longer a safe method.

3. Stay with the baby and see if there are any signs of improvement in breathing.

If you don't get better in a few minutes, please call the emergency number.

If the baby can't breathe at all:

1. Let him lie head down on his thigh and let his head under his chest.

2. Pat the place between his two shoulder blades with the palm of your hand to shake the food out of the trachea.

3. Check the signs of breathing again.

If you don't have it, call the emergency number quickly. Before the ambulance arrives, the staff of the emergency center will guide you to rescue correctly by phone.
