Answer:
the rescuer should check for a pulse to determine what to do next.
Step-by-step explanation:
The next step would be to perform chest compressions, as the person is still unconscious and not breathing effectively on their own. Chest compressions are an essential part of CPR (Cardiopulmonary resuscitation) and are necessary to circulate blood and oxygen to the brain and vital organs. The recommended ratio is 30 compressions to 2 breaths in adult CPR. It is important to continue the cycle of compressions and breaths until the person starts breathing effectively on their own, or until professional help arrives.
