What is a common vital sign finding in infants with bronchiolitis?

In infants with bronchiolitis, an increased respiratory rate is a common vital sign finding. This condition is typically caused by viral infections, commonly respiratory syncytial virus (RSV), which leads to inflammation and increased secretion of mucus in the bronchioles. As a result, infants often exhibit labored and rapid breathing as their bodies attempt to compensate for the narrowed airways and achieve adequate oxygenation.

The elevated respiratory rate reflects the infant's effort to maintain oxygen supply despite the obstruction and increased work of breathing. It's essential for clinicians to monitor this vital sign because significant increases in respiratory rate may indicate worsening respiratory distress, necessitating further medical intervention.

Other vital signs, such as heart rate and temperature, may also be assessed; however, the hallmark of respiratory distress in this population tends to be the elevated respiratory rate associated with the obstructive nature of bronchiolitis.
