What is "high-quality CPR"?

High-quality CPR is defined by several critical components that enhance the chances of survival and recovery for an individual experiencing cardiac arrest. The correct choice emphasizes chest compressions that are deep, fast, and allow for full recoil.

Deep compressions are crucial because they help to effectively circulate blood to vital organs, specifically the brain and heart, during cardiac arrest. The recommendation is for compressions to be at least 2 inches deep in adults and to achieve a rate of 100 to 120 compressions per minute.

Full recoil of the chest between compressions is equally important because it allows the heart to refill with blood, ensuring effectively perfusion during the next compression. Adequate recoil helps optimize blood flow and improves the overall effectiveness of CPR.

While administering breaths is a component of CPR, as well as minimizing interruptions, the foundation of high-quality CPR primarily rests on the quality of chest compressions. Furthermore, CPR should be performed by anyone trained, as bystanders can significantly impact survival even without professional training. The emphasis on quality and technique in chest compressions is what significantly influences positive outcomes in cardiac arrest scenarios.
