What might indicate treatment for an air embolism during an incident?

Difficulty breathing is a critical symptom that can indicate an air embolism. An air embolism occurs when air bubbles enter the bloodstream, which can obstruct blood flow to vital organs, particularly in cases where a diver ascends too quickly. When bubbles form in the lungs or bloodstream, they can cause problems that affect breathing, such as decreased oxygen exchange or blockage of pulmonary blood vessels. Difficulty breathing may be accompanied by other symptoms, but it serves as a key indicator that immediate medical evaluation and intervention are necessary.

While headache, fatigue, and coughing can occur for various reasons, they are not as directly associated with the life-threatening conditions arising from an air embolism as difficulty breathing is. Difficulty breathing signals a more severe response requiring prompt treatment, such as administering oxygen or hyperbaric therapy.
