What is the primary treatment for an asthma exacerbation in the pre-hospital setting?

The primary treatment for an asthma exacerbation in the pre-hospital setting is administering bronchodilators, such as albuterol. Bronchodilators work by relaxing the muscles around the airways, which helps alleviate bronchoconstriction and improve airflow in patients experiencing an asthma attack. These medications provide rapid relief of symptoms and are essential for managing acute episodes effectively.

In contrast, providing high-flow oxygen might help with hypoxia, but it does not directly address the underlying bronchospasm that occurs during an asthma exacerbation. Using steroids orally is more appropriate for long-term management and control of asthma rather than immediate relief during an acute event. Waiting for the patient to stabilize is not a viable option, as timely intervention with bronchodilators is critical to prevent further deterioration of the patient's respiratory status.
