What is the purpose of head-of-bed elevation during endotracheal tube mobilization?

• A. It enhances patient comfort without affecting the tube.
• B. It helps protect the airway and reduce the risk of tube displacement during movement.
• C. It is only for facilitating drain lines.
• D. It should always be minimized.

Answer: (B)

Elevating the head of the bed during airway management with an endotracheal tube is about airway protection during movement. When a patient is repositioned or mobilized, the endotracheal tube can shift, kink, or become dislodged if the head and neck aren’t stabilized. Raising the head of the bed helps anchor the tube relative to the mouth and trachea, reduces torque on the tube with head and neck movements, and makes accidental extubation less likely. It also improves alignment of the airway, which can lower the risk of aspiration during movement.

So, this approach best supports safe mobilization by keeping the airway secure and the tube in the correct position, rather than serving primarily to increase comfort, manage drains, or implying that elevation should be minimized.
