What is the recommended method for controlling bleeding from an extremity wound?

Applying pressure and elevating the limb is the recommended method for controlling bleeding from an extremity wound because it effectively reduces blood flow to the injured area, thereby minimizing blood loss. When pressure is applied to the wound, it helps to compress the blood vessels that are bleeding, which slows down or stops the bleeding. Elevation of the limb complements this process by using gravity to decrease the hydrostatic pressure in the blood vessels, further reducing the likelihood of excessive blood loss.

This approach is particularly effective for minor to moderate bleeding and is often the first step in managing such injuries. It is also a suitable method when a tourniquet is not available or when the situation does not warrant its use, such as in cases of non-life-threatening injuries.

The other methods mentioned have specific uses but are not as effective for immediate bleeding control from an extremity. For instance, using a tourniquet is generally reserved for severe bleeding where direct pressure is insufficient, and applying heat and massage can actually increase bleeding and should not be used in these scenarios. Antiseptic application and bandaging are critical for infection prevention and wound care but come after bleeding control measures have been established.
