Answer :
Final answer:
In the event of a choking victim becoming unresponsive, the prioritized response should involve calling for help and beginning CPR. This emergency procedure maintains the flow of blood until the heart recommences beating. Effective techniques for chest compressions are critical for success.
Explanation:
If a choking victim becomes unresponsive, the rescuer should first call for help or EMS and begin cardiopulmonary resuscitation (CPR).
CPR is an emergency procedure used when the heart stops beating. It combines chest compressions and artificial respiration to maintain blood flow and oxygenation to vital organs. The chest compressions performed in CPR can squeeze blood out of the heart and thereby keep blood flowing until the heart resumes normal function. Applying pressure with one hand on the sternum, between T4 and T9, can efficiently compress the blood within the heart to circulate it into the pulmonary and systemic circuits. This is particularly critical for the brain as irreversible neuron damage can occur within minutes of losing blood flow. In such scenarios, the emphasis is on high-quality chest compressions over artificial respiration.
