What is the first priority if severe hypoxemia is identified?

The first priority when severe hypoxemia is identified is the administration of supplemental oxygenation. This is critical because hypoxemia indicates that there is not enough oxygen in the blood to meet the body's needs, which can lead to tissue damage and organ failure if not addressed promptly. Supplemental oxygen increases the concentration of oxygen in the bloodstream, helping to restore adequate oxygen levels, improve patient outcomes, and stabilize the individual's condition.

In cases of severe hypoxemia, other treatments such as diuretics, increasing fluid intake, or using bronchodilators may be necessary depending on the underlying cause of the hypoxemia, but they are secondary to the immediate need for oxygen. Administering oxygen should always be the first intervention to ensure that vital organs receive the necessary oxygen to function properly.
