What respiratory rate should raise concern in a 2-month-old child?

In a 2-month-old child, a respiratory rate of 30 breaths per minute is considered within the normal range, which typically falls between 30 to 60 breaths per minute. Therefore, this rate would not raise concern. A rate of 20, 24, or 30 breaths per minute is also at the lower end of the normal spectrum but may indicate a concern only if accompanied by other signs of respiratory distress or illness.

In contrast, a respiratory rate of 16 breaths per minute is lower than the typical range for an infant of this age. For young children, especially those under 1 year, a rate below 30 breaths per minute can be indicative of bradypnea and could suggest respiratory depression or other health issues requiring medical attention. Hence, observing a rate of 16 breaths per minute in a 2-month-old is a significant concern and warrants further evaluation to rule out any underlying conditions.

Understanding the normal respiratory rates in infancy is crucial for determining when a child's breathing pattern may need closer monitoring or intervention.
