What is the purpose of practicing high-quality CPR?

Practicing high-quality CPR is primarily aimed at improving the chances of survival for victims of cardiac arrest. High-quality CPR involves effective chest compressions—delivering sufficient depth and rate—as well as allowing full chest recoil between compressions, minimizing interruptions, and providing ventilations as needed. This practice enhances blood flow to vital organs, particularly the brain and heart, which is critical during a cardiac event. By repeatedly honing these skills, responders increase their ability to perform effectively in real-life situations, thereby significantly raising the likelihood of a positive outcome for the patient. This emphasis on survival reflects the fundamental purpose of CPR training, which is to equip individuals with the knowledge and skills necessary to respond appropriately in emergencies.
