What degree will the Stokes litter float?

• A. 30 degrees
• B. 45 degrees
• C. 60 degrees
• D. 90 degrees

Answer: (B)

Buoyancy and trim determine how a flotation litter sits in the water. The Stokes litter is designed with buoyant ends so that, when a patient is placed on it, the combined weight and the buoyant forces settle the litter at a specific angle. About 45 degrees is the balance point where the head and upper torso stay above the water to keep the airway clear, while the body remains supported and the litter remains stable for rescuers to maneuver.

If it were upright (vertical), the airway could be submerged and handling would be awkward; if it were too shallow, the head might not stay out of the water and stability could suffer. Thus, 45 degrees is the angle that best achieves airway protection and controllable stability during rescue.
