What is one of the visible signs of inadequate breathing in infants and children?

Nasal flaring is a significant visible sign of inadequate breathing in infants and children. When a child's breathing is compromised, they may exhibit respiratory distress, which can lead to the use of accessory muscles for breathing. This includes the expansion of the nostrils (nasal flaring) as the body attempts to take in more air to compensate for low oxygen levels or a malfunction in gas exchange. This physiological response indicates that the child is struggling to breathe effectively, suggesting that their respiratory efforts are not sufficient.

In contrast, other signs such as chest rising and falling evenly typically indicate normal breathing patterns, increased interest in surroundings may be a sign of adequate airflow and oxygenation, and consistent pink coloring of the skin generally suggests good oxygenation and circulation. Nasal flaring stands out as a red flag, alerting caregivers or healthcare providers to the potential need for immediate assessment and intervention.
