How deep should chest compressions be performed on an adult?

• A. 1 inch
• B. 1-2 inches
• C. 2-2.5 inches
• D. 2 inches

Answer: (D)

Chest compressions for adults should ideally be performed to a depth of at least 2 inches, as this depth is shown to be effective in generating sufficient blood flow during cardiopulmonary resuscitation (CPR). Research and guidelines from organizations such as the American Heart Association emphasize that compressions should reach a depth of 2 to 2.5 inches to ensure that adequate pressure is applied to the chest, allowing for the heart to pump blood efficiently. This depth not only aids in maintaining circulation to vital organs but also increases the likelihood of survival in cardiac arrest situations. Performing compressions shallower than 2 inches may not effectively circulate blood, diminishing the chances of a successful resuscitation.
