What is the recommended depth of chest compressions in adults during CPR?

The recommended depth of chest compressions in adults during CPR is at least 2 inches (5 cm). This depth is crucial as it allows for effective circulation and ensures that blood reaches vital organs, particularly the heart and brain. Proper depth helps generate adequate pressure within the chest cavity, which is necessary for blood to flow during compressions.

Compressions that are too shallow can lead to ineffective circulation, reducing the chances of successful resuscitation. The emphasis on achieving a minimum depth of 2 inches also aligns with guidelines set by the American Heart Association, which prioritize evidence-based practices in resuscitation to optimize patient outcomes. Ensuring the compressions are at this recommended depth is a foundational element of high-quality CPR, ultimately impacting survival rates in cardiac arrest scenarios.
