High-quality CPR is crucial for improving the chances of survival in a patient experiencing cardiac arrest. A key component of high-quality CPR is performing chest compressions at a rate of at least 100-120 compressions per minute. This rate has been established based on studies showing that maintaining this frequency helps ensure adequate blood circulation to vital organs, particularly the brain and heart, during a cardiac arrest situation.

The consistent flow of compressions within this recommended range helps to create sufficient pressure in the chest to push blood out and throughout the body, which is vital for maintaining perfusion. Additionally, compressions should be of adequate depth and allow for full chest recoil in between compressions, which also optimizes blood flow. When compressions are executed at this rate, it aligns with best practices and guidelines set by organizations like the American Heart Association (AHA) for effective resuscitation efforts.

Other approaches, such as shallow compressions, may compromise the effectiveness of CPR as they may not generate sufficient blood flow. Similarly, intermittent rescue breathing, although important in certain cases, can disrupt the rhythm of high-quality compressions if not synchronized properly. Having two rescuers take turns every minute can improve the quality of chest compressions by reducing fatigue, but the
