Step-by-step explanation:
In a two rescuer scenario, the second rescuer should perform chest compressions at the same rate as the first rescuer, which is 100 compressions per minute.
The recommended depth for chest compressions is at least 5 cm deep. This rate and depth of compressions help in adequately circulating blood and oxygen to the vital organs of the person receiving CPR.
