In suspected Cerebral Arterial Gas Embolism after a scuba incident, which position is recommended for the patient?

• A. Prone
• B. Standing
• C. Supine
• D. Head-down tilt

Answer: (C)

The key idea here is that in cerebral arterial gas embolism, keeping the patient in a neutral, stable position helps preserve cerebral perfusion and avoids movements or angles that could worsen brain injury. A supine position supports steady blood flow to the brain and makes airway management easier, which is crucial while giving 100% oxygen and arranging rapid transfer for hyperbaric therapy. Positions like head-down tilt can raise intracranial pressure or push bubbles in ways that may worsen neurologic injury, while standing or prone can compromise airway security and hemodynamic stability. So, staying supine is the safest, most protective choice until definitive treatment is available.
