What is the best position for the rescuers during two-rescuer CPR for adults?

In two-rescuer CPR for adults, the best position involves one rescuer providing rescue breaths while the other focuses on chest compressions. This approach is beneficial because chest compressions are critical for maintaining blood flow to vital organs, and it is vital to have one person dedicated to ensuring that high-quality compressions are continuously delivered. During the rescue breaths, it allows the rescuer providing breaths to ensure that they are delivered effectively without interrupting compressions for too long.

Having one rescuer dedicated to each task helps maximize the effectiveness of the resuscitation effort. It allows for a more organized effort wherein the rescuer performing compressions can maintain the rhythm and depth necessary for effective compressions, while the other rescuer can use the brief pauses in compressions (twice every five cycles of 30 compressions) to give breaths. This method reduces the time spent with no compressions being delivered, which is critical in improving outcomes for the patient.
