What is the normal pulse rate range for an infant?

The normal pulse rate range for an infant is typically between 80 and 180 beats per minute (bpm). This rate reflects the higher metabolic demands and heart rates of infants compared to older children and adults, whose resting heart rates are lower.

Infants generally have a more significant need for oxygen and nutrients due to their rapid growth and development. Consequently, a faster heart rate allows adequate blood flow to meet these needs. This range can vary depending on factors like age, activity level, and overall health. Thus, the correct response highlights the appropriate physiological considerations for monitoring an infant's vital signs, specifically the heart rate.
