The normal breathing rate for an infant typically ranges from 25 to 50 breaths per minute (bpm). This elevated rate is due to an infant's higher metabolic and oxygen needs compared to adults, as their bodies are still growing and developing rapidly. As they have smaller lungs and a higher surface area to volume ratio, infants require a faster rate of breathing to adequate gas exchange and oxygen delivery throughout their developing bodies. Therefore, recognizing this normal range is crucial for EMTs and other healthcare providers assessing an infant's respiratory status.

In contrast, the other ranges would not accurately reflect a normal respiratory rate for infants. For example, 15-25 bpm is more typical for adults or older children, while 50-75 bpm and 75-100 bpm exceed normal limits, indicating possible respiratory distress or medical problems that would require immediate intervention. Understanding these ranges helps in providing appropriate care and recognizing when an infant may be in distress.
