What is the recommended depth of chest compressions in CPR?

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

Answer: (C)

In CPR, depth of chest compressions is key to moving blood effectively with each push. For an adult, the recommended depth is about 2 inches (5 cm). This depth provides enough pressure to squeeze the heart and propel blood through the body, while keeping injury risk reasonable. Going shallower, like 1 inch, often won’t generate enough blood flow. Going much deeper, such as 3 or 4 inches, can raise the chance of injuries like broken ribs or internal damage without additional benefit. Many guidelines specify a minimum of about 2 inches and caution against excessive depth, with the goal of balancing effectiveness and safety. Remember to maintain a steady rate (roughly 100–120 compressions per minute) and allow full chest recoil between compressions.
