What is the first step to take in the treatment of an air embolism?

The first step to take in the treatment of an air embolism is to clamp the lines. Clamping the infusion lines is crucial because it prevents any further air from entering the vascular system. Air in the bloodstream can lead to serious complications, including obstruction of blood flow to vital organs, which could be life-threatening. By stopping the influx of air, healthcare providers can minimize the risk of further embolization while preparing for additional interventions.

After clamping the lines, other critical steps may follow, such as administering oxygen to reduce hypoxia and changing the patient’s position to help trap the air bubble in a less dangerous area of the circulation. It's important to prioritize clamping the lines to immediately halt the progression of the air embolism.
