What action should be prioritized when treating a patient with respiratory distress from exposure to toxic fumes?

In a scenario involving a patient experiencing respiratory distress due to toxic fume exposure, the most crucial initial action is to establish and maintain an airway. This step is fundamental because respiratory distress can lead to inadequate ventilation and potentially life-threatening hypoxia. By securing the airway, you ensure that the patient can receive adequate oxygenation and ventilation, which is vital for survival.

Once the airway is secured, other interventions such as providing supplemental oxygen and administering bronchodilators can be initiated, depending on the patient's condition and the specific toxic exposure. However, without an adequate airway, these subsequent actions may not be effective or safe.

Transporting the patient to the hospital is important, but it should not take precedence over establishing an airway in an emergency situation, as the patient's immediate needs must be addressed first to prevent deterioration of their condition.
