In managing acute asthma, what should be administered to maintain SpO2 levels?

Maintaining SpO2 levels during an acute asthma attack is crucial for ensuring adequate oxygenation of the patient. The administration of humidified oxygen with a target SpO2 of greater than or equal to 94% is effective because it not only provides essential oxygen to the patient but also helps to moisturizing the airways. This is particularly beneficial in asthmatic patients, as dry air can exacerbate bronchospasm and irritation.

Humidified oxygen can improve comfort and ensure that the respiratory mucosa remains hydrated, which aids in mucus clearance and reduces further airway obstruction. When SpO2 levels fall below 94%, it indicates that the patient is not adequately oxygenated, and providing humidified oxygen can help bring levels back to a safer range without causing hyperoxia or increasing the work of breathing.

In acute asthma management, ensuring that patients have sufficient oxygenation is key to preventing severe hypoxemia and other complications associated with respiratory distress.
