What compression technique is preferred for high-quality CPR?

The preferred technique for high-quality CPR emphasizes pushing hard and fast because this approach is based on the latest guidelines and research. Effective chest compressions are vital for maintaining blood flow to the heart and brain during cardiac arrest.

Pushing hard means applying sufficient force—at least 2 inches deep for adults—while pushing quickly refers to a rate of 100 to 120 compressions per minute. This high rate helps to maximize circulation and increase the chances of survival.

In contrast, techniques such as pushing slowly and gently or at an erratic pace do not provide the necessary blood flow needed to support vital organs. Intermittent compression techniques fail to maintain a consistent supply of blood, which is critical during such emergencies. For these reasons, the combination of hard and fast compressions constitutes the gold standard for CPR quality.
