Dosing and equipment sizing must be adjusted to pediatric physiology and weight. In children, medications are given per kilogram to match their smaller body mass and different drug handling, preventing underdosing or dangerous overdosing. Equipment must be sized to fit smaller airways, limbs, and torsos to ensure effective treatment and avoid injury. Because pediatric patients vary widely in size even within the same age, relying on adult doses or age alone leads to inappropriate dosing and ill-fitting equipment.

Using adult doses for simplicity ignores crucial pharmacologic differences, avoiding weight-based calculations misses the dose the child actually needs, and determining size by age alone can be wrong due to wide variability in weight and anatomical development.
