How long should you leave on a pressure bandage?

A pressure bandage should typically be left on for 24 to 48 hours, depending on the severity of the injury and the advice of a healthcare professional. It's important to monitor the area for signs of increased swelling, pain, or infection. If any of these occur, or if the bandage becomes saturated with blood, it should be reassessed and potentially changed sooner. Always follow the specific guidance given by a medical provider for the best outcome.
