In an emergency situation, what is the first action to take after confirming a choking infant?

In the case of a choking infant, the immediate action to take after confirming the situation is to begin back blows. This technique is crucial as it can help dislodge the object that is causing the choking. By administering back blows while the infant is in a position that allows gravity to assist, you can create enough force to potentially clear the airway.

Calling for help or checking for responsiveness are important steps in CPR training, but they do not directly address the immediate threat of choking. Making the infant cough is also not suitable in this situation; coughing is usually more effective for older children and adults who are capable of using their own airway clearing mechanisms. Infants lack the coordination or strength to effectively cough out an obstruction, which is why back blows are the recommended first action.
