How deep should you compress the chest during closed chest massage?

• A. 1/2 to 1 inch
• B. 1 to 1 1/2 inches
• C. 1 1/2 to 2 inches
• D. 2 to 2 1/2 inches

Answer: (C)

The recommended depth for chest compressions during closed chest massage, also known as cardiopulmonary resuscitation (CPR), is important for ensuring that adequate blood flow is maintained to vital organs during a cardiac arrest. Compressing to a depth of 1 1/2 to 2 inches is recommended because this depth is sufficient to create the necessary pressure in the thoracic cavity, allowing for effective circulation and blood return to the heart. When compressions are performed at this depth, it helps ensure that the heart can adequately fill and eventually pump blood effectively when the compressions are released. Deeper compressions beyond 2 inches can lead to complications, such as broken ribs or damage to the internal organs, while compressions shallower than 1 1/2 inches may not generate enough pressure to maintain perfusion during cardiac arrest scenarios. The choice of 1 1/2 to 2 inches is consistent with guidelines from recognized authorities such as the American Heart Association, which emphasizes both the depth and the rate of compressions for optimal outcomes in CPR situations.
