If a victim shows signs of severe breathing complications, what is your priority action?

Administering oxygen is the priority action in the presence of severe breathing complications because it addresses the immediate need for the victim to receive adequate oxygenation. When someone experiences significant difficulty in breathing, such as in cases of asthma attacks, allergic reactions, or other respiratory issues, providing supplemental oxygen can help stabilize their condition by enhancing their ability to breathe and improving the oxygen supply to vital organs.

While calling emergency services is essential for ongoing medical support, it may not directly address the urgent need for oxygen. Reassuring the passenger is important for comfort, but it does not treat the root cause of the breathing complications. Performing the Heimlich maneuver is indicated for cases of choking, which does not apply to situations involving severe breathing issues unrelated to an obstruction. Thus, administering oxygen is the most immediate and effective way to assist someone experiencing severe breathing difficulties.
