Which condition is NOT typically treated with a ventilator?

Mild allergic rhinitis is not typically treated with a ventilator because it is primarily a condition involving nasal inflammation and congestion due to allergic reactions, usually managed with antihistamines, nasal corticosteroids, and avoidance of allergens. Respiratory support with a ventilator is used for severe respiratory failures where oxygenation and ventilation are critically compromised—situations that are not characteristic of mild allergic rhinitis.

On the other hand, conditions such as acute respiratory distress syndrome, COPD exacerbations, and severe asthma can lead to significant respiratory distress or respiratory failure, making ventilatory support necessary to ensure adequate oxygenation and carbon dioxide removal. These conditions require more intensive management and monitoring in a hospital setting, often necessitating the use of mechanical ventilation.
