What is the first step in applying the pneumatic tourniquet?

The first step in applying the pneumatic tourniquet involves padding the limb where the tourniquet is to be wrapped with Webril. Padding is essential because it helps to protect the skin and underlying tissues from potential damage caused by the pressure of the tourniquet. This step is crucial in preventing skin breakdown and pressure injuries, especially in cases where the tourniquet will be used for an extended period.

Using Webril or similar padding materials ensures a cushioning effect and distributes the pressure more evenly over the limb. This preparation aids in maintaining blood flow to critical tissues and reduces the risk of complications associated with tourniquet application, such as nerve injury or tissue ischemia.

The subsequent steps would typically involve securing the tourniquet above the padded area, wrapping it correctly to ensure an effective seal, and then inflating it as needed, but padding is the foundational initial action.
