In the ICP protocol, what head-of-bed elevation is recommended?

• A. Elevate Head of Bed to 60°
• B. Elevate Head of Bed to 15°
• C. Elevate Head of Bed to 30°
• D. Keep head flat

Answer: (C)

Managing intracranial pressure hinges on improving venous drainage from the brain while keeping cerebral perfusion adequate. Elevating the head of the bed to about 30 degrees provides a balance: it helps the brain drain venous blood, which can lower ICP, but it doesn’t overly reduce arterial inflow or mean arterial pressure, so cerebral perfusion is preserved. Raising the head much higher, like 60 degrees, can drop blood pressure enough to reduce cerebral perfusion, which can be harmful. Conversely, a very shallow elevation, such as 15 degrees, may not sufficiently aid venous outflow and ICP can stay elevated. Keeping the neck in a neutral position also helps avoid venous outflow obstruction. So, around 30 degrees is the recommended level.
