What is a common supportive treatment for croup infections?

Humidified oxygen is a common supportive treatment for croup infections because it helps alleviate the symptoms associated with airway inflammation and obstruction, which are characteristic of croup. The moist air can soothe an irritated throat and help keep the airways open, making it easier for the patient to breathe. This form of treatment can be particularly beneficial during the acute phase of croup when the airway is swollen, and the patient may experience stridor (a high-pitched wheezing sound) or difficulty breathing.

In contrast, antibiotics are not effective because croup is usually caused by viral infections, not bacterial ones. Inhaled corticosteroids may be used in some situations to reduce airway inflammation, but they are not considered a first-line supportive treatment. Analgesics can help alleviate discomfort and fever but do not address the airway issues directly. Therefore, humidified oxygen is the most supportive and symptom-relieving option for managing croup effectively.
