What is the correct sequence of cpr for an adult, or a child or an infant, when two rescuers are present?

The correct sequence for an adult CPR when two rescuers are present is:

place the victim on the floor or on a flat surface. One rescuer should place his or her hand just above the victim's sternum, just between the nipples, and place the second hand on top of the first with fingers interlaced. The other rescuer should deliver oxygen through braces or mouth-to-mouth resuscitation.The first rescuer should direct his body directly over his hands so that his arms are straight and firm. Next, the rescuer should do 30 chest compressions while oxygen is administered.If nothing works, rescuers should use an automatic external defibrillator until vital signs return, otherwise the individual should be taken to a medical facility.

Explanation:

Cardiopulmonary resuscitation (CPR) consists of a series of maneuvers performed by health professionals or lay people to reverse cardiopulmonary arrest (CRP) and maintain adequate oxygenation and tissue perfusion. CPR can be applied in or out of hospital settings and is divided into advanced life support (VAS) and basic life support (SBV), respectively. The emphasis on good quality CPR can save lives.

The two definitions are not animate or lifeless or the other definition is spiritless or sluggish.
