Final answer:
CPR should be administered to children and infants if they are unconscious, show no pulse, or are not breathing normally. It is a critical emergency procedure that supports the victim's blood circulation and breathing, increasing the chances of survival by maintaining brain function.
Step-by-step explanation:
In both children and infants, two minutes of CPR should be given if: (d) All of the above. This means CPR should be administered if the victim is unconscious, has no pulse, or is not breathing normally.
CPR is critical as it helps to manually compress the blood within the heart, propelling it into the systemic and pulmonary circuits, which is particularly critical for maintaining brain function, as brain cells can start dying within minutes without oxygen.
It's essential to note that immediate action is crucial, and rescuers should perform CPR as soon as they determine the individual is not responsive or not breathing adequately.
While it is sometimes common for untrained individuals to cause harm, high-quality chest compressions are prioritized over artificial respiration, and CPR should continue until the victim regains spontaneous activity or is declared deceased by healthcare professionals.
