Final answer:
CPR is required for a victim who is unresponsive with no normal breathing and no pulse. Proper CPR technique involves applying pressure to the sternum between the lines at T4 and T9 to manually compress the heart. Training is crucial to avoid injuries and ensure effectiveness, with courses available at various locations.
Step-by-step explanation:
The victim who requires CPR is A. A victim who is unresponsive with no normal breathing and no pulse. Cardiopulmonary resuscitation (CPR) is a life-saving technique used when the heart has stopped and the victim is unresponsive without natural breathing, essentially in a state of cardiac arrest. During CPR, pressure is applied with the hands on the sternum between the lines at T4 and T9, which will manually compress the heart and push blood into the pulmonary and systemic circuits, especially critical for brain function since neurons can begin to die within minutes without blood flow.
Proper training in CPR is essential for both safety and effectiveness because improper technique can cause serious injury, such as broken ribs or damage to the liver. CPR courses are offered in various locations to ensure that the public, as well as medical personnel, receive certification in the correct application of CPR. CPR is continued until the victim regains spontaneous heart contractions or is declared dead by a healthcare professional.
Remember:
- Victim with no pulse and no breathing needs CPR
- Proper training in CPR technique is vital
- High-quality chest compressions are emphasized over artificial respiration
