What is an early sign of respiratory distress in an infant?

Nasal flaring is a key early sign of respiratory distress in an infant. It occurs when an infant's nostrils widen during inhalation, indicating that they are struggling to get enough air. This physiological response happens as a means to increase airflow and can suggest that the infant is experiencing difficulty breathing, such as from an obstructed airway or reduced lung function.

Recognizing nasal flaring is crucial for early intervention, as it can help healthcare providers quickly assess the severity of respiratory distress and decide on timely management strategies. In infants, whose respiratory systems are still developing, even minor changes such as nasal flaring can signal significant respiratory issues that require prompt attention.
