What is the correct compression depth for adult CPR according to ECC Test 4 guidelines?

• A. 1 inch (2.5 cm)
• B. 2 inches (5 cm)
• C. 3 inches (7.5 cm)
• D. 2.5 inches (6 cm)

Answer: (B)

The correct compression depth for adult CPR, as outlined in the ECC Test 4 guidelines, is 2 inches (5 cm). This depth is critical because it ensures that enough force is applied to circulate blood effectively in the adult body during cardiac arrest. By compressing the chest to the recommended depth, rescuers can create sufficient pressure in the thoracic cavity, allowing for better blood flow to vital organs such as the brain and heart. Maintaining this depth is also important to avoid inadequate compressions, which can lead to poor outcomes in resuscitation efforts. The guidelines emphasize the significance of reaching this specific depth consistently while allowing complete chest recoil between compressions, as this aids in optimizing blood circulation. This emphasis on technique not only improves the chances of survival for the patient but also aligns with international resuscitation standards established by organizations like the American Heart Association (AHA) and the European Resuscitation Council (ERC).
