pressure ulcer staging
1. intact skin, non blanching redness in local area. dark pigment 2 = partial thickness loss of dermis = shallow open ulcer with red/pink wound bed. / looks like serum blister 3 = full thickness. subcut fat. 4 = full thickness with exposed bone, tendon or muscle +/- sloughing 5- unstageable. full thick with bas e= necrotic
