During CPR, what should the focus be when performing chest compressions?

The most critical aspect of chest compressions during CPR is achieving a depth of at least 2 inches. This depth is essential for generating adequate blood flow to vital organs, particularly the brain and heart, during cardiac arrest. Compressions that are too shallow may not be effective in circulating blood, which significantly reduces the chances of survival for the individual in need of resuscitation. The proper technique not only involves the depth but also the rate and allowing for full chest recoil between compressions to maximize blood flow.

While maintaining a steady rhythm and communicating with the team are important for overall coordination during CPR, they do not take precedence over the actual depth and quality of compressions. Similarly, focusing solely on ventilation does not adequately address circulation, which is crucial in the first moments of a cardiac arrest situation. The concept of a compress-and-ventilate ratio is relevant, but it is also secondary to ensuring that compressions are performed correctly, with the requisite depth being the priority during the initial phases of CPR until advanced help arrives.
