Abstract
Dressings, systems, and methods are disclosed in some embodiments that involve treating a tissue site with reduced pressure wherein the dressing includes a dressing reduced-pressure indicator that allows one to ascertain that the reduced pressure applied at the dressing is greater than a threshold reduced pressure. The dressing reduced-pressure indicator may include a moving member that is adapted to move under reduced pressure and a visual indicator associated with the moving member. Another embodiment uses an electro-mechanical indicator to provide a powered visual alert or audible alert or another output signal. Other dressings, systems, and methods are disclosed.
