What are the four age groups defined for CPR?

The correct answer identifies four age groups that are crucial in the context of CPR (Cardiopulmonary Resuscitation) to ensure appropriate techniques and interventions are used based on the patient's age. The classifications of natal care, less than 1 year, 1-7 years, and 8 years to adult effectively delineate the differences in anatomical and physiological characteristics among these age groups.

Infants (under 1 year) require specific techniques due to their smaller size and differing physiology, while children aged 1 to 7 have different CPR protocols that account for their growth and development. For individuals aged 8 and older, standard adult CPR techniques are applicable as their body composition is much closer to that of adults. Understanding these distinctions is crucial for providing effective emergency care and maximizing the chances of survival for individuals in different developmental stages.
