Final answer:
The age of the victim determines whether to give adult or pediatric CPR, with children generally receiving pediatric CPR and those over 8 or who've gone through puberty receiving adult CPR.
Step-by-step explanation:
The determining factor for whether a victim should receive adult or pediatric CPR is the age of the victim. In general, adult CPR is appropriate for anyone who is over 8 years old or has gone through puberty, while pediatric CPR is for child and infant victims. For instance, children ages 0 to 2.5 would receive infant CPR, typically involving gentle chest compressions and rescue breaths. Children ages 2.5 to 6 and children ages 6-13 would receive child CPR with modifications in compression depth and breath size. Adolescents ages 13-20 should be treated with adult CPR if they are significantly developed and have signs of having gone through puberty.
