Compression depth for Adult CPR?

Compression depth for Adult CPR?

• A. At least 2 in/5 cm, no more then 2.4 in/6 cm
• B. At least 1 in
• C. At least 3 in
• D. At least 4 in

Answer: (A)

The key idea is the recommended chest compression depth for adults during CPR. For adults, you should compress the chest at least 2 inches (5 cm) but not more than about 2.4 inches (6 cm) with each push. This range provides enough force to circulate blood effectively while reducing the risk of injury from pushing too deep. A depth of only 1 inch is too shallow to generate adequate blood flow, while depths of 3 inches or 4 inches go beyond the upper limit and increase the chance of damage to ribs or internal organs. So the best answer describes compressions within the 5–6 cm range.
