Which technique is key for successfully performing a backboard pullout extrication?

Employing the pool edge as a seesaw to slide the board out is crucial for successfully performing a backboard pullout extrication because it helps to reduce the effort required to lift and move the board from the water to the deck. By using the edge of the pool in this way, rescuers can create a pivot point that allows them to leverage the weight of the patient on the board more effectively. This technique not only minimizes physical strain on the rescuers but also ensures a smoother transfer of the individual onto the deck without causing additional injury.

This method is particularly important in scenarios where the patient may have a spinal injury, as it allows for a controlled and stable movement, reducing the risk of exacerbating any potential injuries during the extraction. In contrast, other options such as using multiple rescuers or securing the board tightly may be helpful but do not address the mechanical advantage that the pool edge provides in assisting with the extrication process.
