What percentage of bleeding can be controlled by direct pressure?

Direct pressure is a fundamental technique used to control bleeding and is effective for a significant majority of bleeding incidents. When applied correctly, direct pressure can control approximately 95% of external bleeding scenarios, particularly for wounds that are not severe or do not have significant damage to major blood vessels. This method involves applying firm pressure over the wound using a clean cloth or bandage, effectively helping to stop blood flow.

The effectiveness of direct pressure stems from its ability to create localized compression, which helps to promote clotting and minimize the loss of blood. The tactic is straightforward and does not require specialized medical equipment, making it accessible in various emergency situations. Knowing that direct pressure can control such a high percentage of external bleeding reinforces the importance of this skill for Emergency Medical Dispatchers and responders in assessing and advising on first aid measures.
