Pressure Sores. This can be a little tricky. There are six categories of pressure ulcers: stages 1, 2, 3, 4, unable to stage and deep tissue injury. There are a pressure injuries that do not necessarily need to be covered. For example, a stage 1 ulcer does not have a break in the skin and can be left uncovered in many cases. Some ulcers are left uncovered because of location but have protective creams applied.
Get the pressure off. The first thing to do is keep the pressure off at all times! some pressure wounds will heal without doing anything else, however many additional treatments are available to speed healing along especially negative pressure (vac) but the exact treatment must be customised to the individual wound, most if not all require coverage to keep in place and control drainage.
