What does effective CPR aim to maintain during a cardiac arrest situation?

• A. Normal body temperature
• B. Oxygenated blood flow to the brain
• C. Regular heart rhythm
• D. Physical strength of the rescuer

Answer: (B)

Effective CPR aims to maintain oxygenated blood flow to the brain during a cardiac arrest situation. When the heart stops beating effectively, blood circulation ceases, leading to a lack of oxygen being delivered to vital organs, especially the brain. Without oxygen, brain cells begin to die within minutes, which can result in irreversible damage or death. By administering CPR, the goal is to artificially circulate blood and keep it flowing to the brain and other vital organs until professional medical help arrives. This is crucial because preserving brain function is vital for the patient's chance of recovery. The rhythm of the heart or the physical strength of the rescuer, while important in their own contexts, do not directly address the critical need for ongoing oxygenated blood flow during cardiac arrest. Maintaining normal body temperature, although beneficial, is not a primary focus of CPR in the immediate emergency response context.
