What head position is recommended during an acute stroke assessment?

• A. Elevate head no more than 30 degrees
• B. Elevate head to 60 degrees
• C. Flat supine with head lower than feet
• D. Head raised to 90 degrees

Answer: (A)

Positioning during an acute stroke assessment aims to optimize cerebral perfusion while managing intracranial pressure. Elevating the head of the bed to about 30 degrees reduces intracranial pressure by promoting venous drainage, without excessively lowering cerebral perfusion pressure. Raising the head too much (60 or 90 degrees) can decrease the blood flow to the brain by lowering mean arterial pressure relative to the intracranial pressure, while a flat position or putting the head lower than the feet can increase intracranial pressure and worsen edema or airway risk. So, about 30 degrees of head elevation is the best choice to balance perfusion and pressure.
