What should be done if active bleeding occurs?

When addressing active bleeding, the best practice is to apply pressure to the wound while ensuring that it is properly managed. Redressing over an existing dressing is effective because it allows for the absorption of blood without disrupting the clotting process that may already be occurring. By placing additional pressure and material on top of the existing dressing, you can help contain the bleeding, reduce the risk of further injury, and support the body's natural healing mechanisms.

This method is important because changing the dressing completely could expose the wound to air and bacteria, potentially dislodging any clots that have begun to form, which may increase bleeding. Leaving the wound without any dressing would also be inappropriate, as it could lead to further contamination and infection. While applying pressure and waiting for professional help is crucial, it's primarily the act of redressing that helps control the bleeding effectively in the interim.
