Describe the proper technique for a two-rescuer CPR.

In a two-rescuer CPR scenario, the most effective approach is for one rescuer to focus on providing high-quality chest compressions while the other rescuer administers rescue breaths. This division of tasks ensures that both key components of CPR—compressions and breaths—are performed effectively and efficiently.

The rescuer performing compressions is responsible for maintaining a proper rhythm and depth of compressions, which is crucial for maintaining blood flow to vital organs. Meanwhile, the second rescuer can focus on delivering rescue breaths at the appropriate intervals, ensuring that the patient is receiving sufficient oxygen. This strategy decreases the fatigue level of both rescuers, allowing them to sustain the effort over a longer period, enhancing the overall effectiveness of the CPR being administered.

It's important to avoid scenarios where both rescuers focus exclusively on one aspect, such as compressions or rescue breaths alone. This not only would provide inadequate support but also may lead to improper timing or interruptions in the crucial cycle of CPR. The balanced approach of alternating roles while maintaining the different components of CPR significantly improves the chances of survival for the person in cardiac arrest.
