What is the age definition of an infant in basic life support terminology?

In basic life support terminology, an infant is defined as a child who is less than 1 year old. This definition is important for first responders and healthcare providers, as it determines the appropriate techniques and protocols to use when administering care. Infants have different anatomical and physiological considerations compared to older children and adults, which affects how CPR is performed and how other interventions are carried out.

For instance, the compression depth, ventilation techniques, and the use of equipment differ significantly between infants and individuals in other age groups. By clearly defining an infant as anyone under 1 year old, it helps ensure that responders are prepared to offer first aid that is suitable for this particularly vulnerable age group.
