Which of the following is NOT a step in treating air embolism?

In treating an air embolism, the approach focuses on rapidly delivering medical care to mitigate complications from gas bubbles entering the vascular system. Providing oxygen in a hyperbaric chamber is critical as it helps reduce the size of the air bubbles and improves the body's ability to absorb nitrogen, promoting recovery. Positioning the individual with their head down and feet up can assist in preventing the embolism from reaching vital organs and encourages blood flow back to the heart. Laying the person on their back may also be a standard treatment position allowing for ventilation.

Contrarily, administering fluids orally is not a step in treating air embolism because the condition requires immediate medical attention and often intravenous therapies rather than oral hydration. Time is of the essence in managing air embolism safely and effectively, which is why interventions may involve oxygen therapy and specific positioning rather than oral fluids — which could delay necessary treatment.
