What is the recommended chest compression depth for adult CPR?

• A. 1-1.5 inches
• B. 2-2.4 inches
• C. 1.5-2 inches
• D. 3-3.5 inches

Answer: (B)

The recommended chest compression depth for adult CPR is 2 to 2.4 inches. This depth is indicated in current guidelines because it has been shown to provide effective circulation during cardiac arrest by ensuring that sufficient blood flow reaches vital organs. A depth of at least 2 inches allows the compressions to create adequate pressure in the thoracic cavity, facilitating the return of blood to the heart and ensuring that vital organs receive the oxygenated blood they need during the critical moments of cardiopulmonary resuscitation. Furthermore, compressions that are too shallow may not generate enough pressure to maintain effective circulation, while compressions that are too deep can potentially cause injuries to the victim's ribs or internal structures. Hence, adhering to the guideline of compressing to a depth of 2 to 2.4 inches strikes a vital balance between effectiveness and safety. This guideline reflects substantial research and consensus within the emergency response and cardiology communities, emphasizing the importance of high-quality CPR in enhancing survival rates following cardiac arrest.
