What is the recommended chest compression depth for an adult in CPR?

Explanation:
In adult CPR, compressions must be deep enough to push blood out of the heart without causing unnecessary injury. The recommended depth is about 2 inches (5 cm). This depth helps generate sufficient blood flow during each compression. Going shallower, like about 1 inch, reduces the amount of blood moved with each press. Going much deeper, around 3 or 4 inches, increases the risk of harming the chest or internal structures and isn’t shown to improve outcomes beyond the safe 2-inch target. Among the given options, about 2 inches (5 cm) best fits the guideline and yields effective compressions.
