Which of the following is a typical respiratory pattern observed in Bronchiolitis/RSV?

In cases of bronchiolitis, particularly those caused by respiratory syncytial virus (RSV), a typical pattern observed is tachypnea, which refers to an increased breathing rate. This is due to the obstruction and inflammation of the small airways in the lungs, leading to a heightened effort to maintain adequate ventilation. The intermittent cough can occur as a result of irritation in the airways and is common in respiratory infections.

Tachypnea is a key sign as the body attempts to compensate for impaired gas exchange and lower oxygen levels, which occur due to airway obstruction. The intermittent cough also (along with wheezing) can help to clear mucus from the airways that accumulate because of the inflammatory response to the viral infection.

The other options do not accurately reflect the typical respiratory patterns seen in bronchiolitis caused by RSV. Understanding the typical presentations helps in distinguishing the condition and providing appropriate care and interventions.
