Final answer:
In CPR, multiple rescuers should switch compressors every 2 minutes, approximately every 5 cycles, to prevent fatigue and ensure effective chest compressions.
Step-by-step explanation:
In CPR (Cardiopulmonary Resuscitation), when multiple rescuers are present, they should switch compressors every 2 minutes, which is approximately every 5 cycles. This allows each rescuer to maintain their energy and prevent fatigue, ensuring effective and continuous chest compressions. Continuous chest compressions are crucial for keeping the blood flowing to the vital organs during cardiac arrest
