How many inches in depth do you go for CPR on an adult?

• A. 1 inch
• B. 3 inches
• C. 2 inches
• D. 4 inches

Answer: (C)

Adult CPR chest compression depth is what this question focuses on. The recommended depth is about 2 inches (roughly 5 cm) with each compression, allowing the chest to recoil fully between pushes. This depth is deep enough to generate adequate blood flow without increasing the risk of serious injury that can come with much deeper compressions. Shallow compressions, like 1 inch, don’t move enough blood, while much deeper compressions (around 3 or 4 inches) raise injury risk without additional benefit in standard guidelines. Maintain a steady rate of 100–120 compressions per minute and ensure complete chest recoil after every compression.
