Reducing interruptions during CPR helps maintain perfusion to which organs primarily?

Reducing interruptions during CPR helps maintain perfusion to which organs primarily?

• A. Lungs and kidneys
• B. Liver and spleen
• C. Brain and heart
• D. Muscles and bones

Answer: (C)

The main idea is that during CPR the goal is to keep the blood flowing to the organs that are most vulnerable to lack of oxygen, especially the brain and the heart. Continuous chest compressions help preserve coronary and cerebral perfusion pressures, so the heart keeps receiving blood and the brain remains oxygenated. Any unnecessary pauses cause a drop in arterial pressure, making it harder to maintain blood flow when compressions resume and reducing the chances of returning spontaneous circulation and minimizing brain injury. While all organs need blood, the brain and heart are the ones most critically affected by interruptions, so they’re the primary targets of sustained perfusion during CPR.
