During a vasovagal syncope, which recovery position facilitates return of cerebral perfusion?

• A. Standing upright.
• B. Supine position.
• C. Trendelenburg (head-down) position.
• D. Prone position.

Answer: (B)

When vasovagal syncope happens, the body’s reflex causes a drop in heart rate and blood pressure, which reduces blood flow to the brain. Placing the person flat on their back (supine) helps blood return to the heart from the legs and trunk, restoring central blood volume and improving cerebral perfusion so the person wakes up and recovers more quickly. Standing upright keeps blood pooled in the legs and can prolong the dizziness or loss of consciousness. A Trendelenburg position (head-down) can temporarily increase brain blood flow but isn’t routinely used in recovery because it can cause breathing difficulties and other risks, and it’s not as supportive for overall stability. The prone position doesn’t aid venous return to the heart in a way that helps brain perfusion return promptly. Therefore, lying supine best facilitates the recovery of cerebral perfusion after a vasovagal episode.
