How long should pressure be maintained on a wound after applying a hemostatic dressing?

Maintaining pressure on a wound after applying a hemostatic dressing is crucial for effective control of bleeding. Three minutes is recommended because it provides enough time for the hemostatic agents within the dressing to properly activate and promote clotting. The pressure helps to close off blood vessels and initiate the body's natural healing processes, allowing the blood to coagulate effectively.

In tactical situations, expediency is vital, but so is ensuring that bleeding is adequately controlled. Shorter durations may not be sufficient for establishing effective hemostasis, while longer durations could delay further medical interventions that might be necessary if the casualty's condition does not stabilize. The three-minute guideline balances these needs, assisting in the prevention of significant blood loss while ensuring tactical readiness for further treatment if necessary.
