Answer:
The next step is to blow air into the mouth of the unresponsive child.
Step-by-step explanation:
If you are alone and identified that a child is unresponsive, the first step you would do will surly be calling 911. After calling 911, you should give chest compression to the child. Chest compression is applying pressure to the chest of the patient who is unresponsive, in intervals. This is done to put pressure on heart and make it start. After this step, if the person is still not responsive, the next step is to blow the air into the mouth of that person. This will give a pressure of air to the lungs. This step should be repeated again and again till rescue arrives.
