What age defines an infant for Basic Life Support care?

An infant is defined as a child under the age of 1 for Basic Life Support (BLS) care. This classification is important because the techniques used in BLS for infants differ significantly from those used for older children and adults. The physiological differences in size, anatomy, and response to resuscitation necessitate specific approaches tailored to this age group.

The reason this age cutoff is significant is because it marks a developmental stage where infants have unique characteristics, such as a smaller airway and softer ribs, requiring distinct techniques for effective chest compressions and ventilation. Understanding this definition ensures that caregivers provide appropriate and effective care during emergencies involving young children.

The other definitions of infant may lead to misunderstandings regarding the specific needs and techniques required for infants versus older children. For example, defining an infant as being from birth to 2 years could lead to applying inappropriate methods designed for the older segment of that range, while definitions that start at age 1 overlook the critical care requirements of the first year of life.
