What is the recommended position for a casualty who is in shock, absent spinal injury?

• A. Supine with legs elevated about 6-12 inches to improve venous return
• B. Head-down position with legs elevated
• C. Left lateral decubitus with head down
• D. Sitting upright with legs dangling

Answer: (A)

In shock, the priority is to maximize blood returning to the heart to improve circulation to vital organs. If there’s no concern for spinal injury, the best positioning is to lie the casualty flat on their back and elevate the legs about 6 to 12 inches (roughly 15–30 cm). Elevating the legs uses gravity to move blood from the legs toward the central circulation, increasing venous return (preload) and helping the heart pump more effectively. Why other positions aren’t as good: a head-down position with the legs elevated might seem to boost return, but it can worsen breathing, raise intracranial pressure, and increase the risk of vomiting or aspiration. A left lateral decubitus position with the head down doesn’t optimize perfusion and can complicate airway management. Sitting upright with legs dangling reduces venous return, which can drop blood pressure further and worsen shock.
