What is a key indication for using direct pressure on a wound?

Using direct pressure on a wound is most critical when there is pulsating arterial bleeding. This type of bleeding indicates that a major artery has been compromised, which can lead to rapid and significant blood loss. Applying direct pressure helps to control this bleeding by compressing the damaged vessel against surrounding tissues, assisting in the clotting process and preventing further blood loss.

The urgency of using direct pressure in cases of pulsating arterial bleeding aligns with the need for quick intervention to stabilize the patient. If left uncontrolled, this type of bleeding could quickly become life-threatening, making it essential to act promptly by applying pressure to the wound. In contrast, while minor cuts and abrasions and significant non-pulsating hemorrhage may also benefit from direct pressure, they do not present the same immediacy of risk as roaring arterial bleeding. Additionally, relying on a tourniquet as the first option is usually not recommended unless direct pressure fails or is not applicable, because tourniquets can cause significant complications if used unnecessarily.
