In the context of cardiac arrest, what does the term "high-quality CPR" refer to?

High-quality CPR is vital for increasing the chances of survival in cases of cardiac arrest, and it specifically emphasizes the importance of performing chest compressions that are both effective and efficient. This involves performing chest compressions at a rate of 100-120 per minute, which has been shown to maximize blood flow to the brain and vital organs during cardiac arrest. Additionally, it is crucial that these compressions are delivered with sufficient depth, typically at least 2 inches (5 cm) for adults, to ensure adequate circulation.

The other options do not align with the current CPR guidelines established by organizations such as the American Heart Association. For instance, chest compressions at a rate of 60-80 per minute would be considered too slow and ineffective in maintaining circulation during cardiac arrest. Similarly, while rescue breaths are part of the CPR sequence, the emphasis in high-quality CPR is to prioritize chest compressions, and the option regarding rescue breaths does not reflect the push for continuous compressions. Lastly, while using an AED (Automated External Defibrillator) is essential in the chain of survival, the timing of using it immediately after starting compressions isn't aligned with the focus on high-quality CPR, which prioritizes effective compressions over immediate defibrillation.
