Why is the head of the bed often raised to 30 degrees after stroke?

• A. To improve patient comfort
• B. To reduce edema
• C. To reduce aspiration risk and address cardiopulmonary issues and intracranial pressure
• D. To accelerate metabolism

Answer: (C)

Elevating the head of the bed to about 30 degrees uses gravity to promote venous drainage from the brain, which lowers intracranial pressure after a stroke. Lower ICP helps protect brain tissue from further injury and can improve overall cerebral perfusion by preventing pressure from compromising blood flow. At the same time, this position reduces the risk of aspiration during swallowing or feeding and can improve cardiopulmonary function by aiding diaphragmatic excursion and oxygenation. It’s not primarily about comfort, edema in the limbs, or metabolism; those are not the main goals here. If ICP rises or airway protection is compromised, keeping the head elevated helps mitigate those risks while still aiming to maintain adequate cerebral perfusion.
