Question

why children's blood contain more oxygen than adults?

Answer 1

Because cardiac output to blood volume ratio is higher in children than in adults

Answer 2

Children and adults have different physiologic and hematologic systems, which impacts therapeutic interventions and their efficacy. In addition, children of different ages have different physiology and anatomy, which further complicates treatment. For example, an infant has a higher metabolic rate than an 8-year-old, a larger body surface area to mass ratio, and a markedly smaller blood volume. Hence, different strategies need to be employed when treating children of different ages. These differences are accentuated in burn injury, which further alters metabolism, anatomy, and physiology.
