Which of the following is NOT a key action to provide high-quality CPR?

In high-quality CPR, one critical component is ensuring that compressions are performed at an appropriate depth. The correct depth for adult patients is at least 2 inches, but typically it should not exceed about 2.4 inches. The guideline specifying at least 3 inches as a depth for compressions is inaccurate, as it can potentially lead to adverse effects, such as rib fractures or damage to internal organs. Therefore, while proper compression depth is essential for effective CPR, a requirement of at least 3 inches does not align with established guidelines.

The other options mentioned – performing compressions at a rate of 100 to 120 per minute, allowing the chest to fully recoil between compressions, and minimizing interruptions in compressions – are all critical for ensuring effective circulation during CPR. By maintaining the recommended compression rate, allowing full recoil to ensure the heart can refill with blood, and minimizing interruptions, care providers can significantly increase the chances of survival for the patient experiencing cardiac arrest.
