Stage I is the most superficial, indicated by non blanchable redness that does not subside after pressure is relieved. This stage is visually similar to reactive hyperemia seen in skin after prolonged application of pressure. Stage I pressure ulcers can be distinguished from reactive hyperemia in two ways: a) reactive hyperemia resolves itself within 3/4 of the time pressure was applied, and b) reactive hyperemia blanches when pressure is applied, whereas a Stage I pressure ulcer does not. The skin may be hotter or cooler than normal, have an odd texture, or perhaps be painful to the patient. Although easy to identify on a light-skinned patient, ulcers on darker-skinned individuals may show up as shades of purple or blue in comparison to lighter skin tones.
Stage II is damage to the epidermis extending into, but no deeper than, the dermis. In this stage, the ulcer may be referred to as a blister or abrasion.
Stage III involves the full thickness of the skin and may extend into the subcutaneous tissue layer. This layer has a relatively poor blood supply and can be difficult to heal. At this stage, there may be undermining damage that makes the wound much larger than it may seem on the surface.  
Stage IV pressure ulcerStage IV is the deepest, extending into the muscle, tendon or even bone.
Unstageable pressure ulcers are covered with dead cells, or eschar and wound exudate, so the depth cannot be determined.


第一阶段是最肤浅的，表明非blanchable发红，不消退后压力缓解。这个阶段的视觉类似反应性充血后出现皮肤长期应用的压力。第一期压疮可区别于反应性充血的方法有两种： 1 ）反应性充血解决本身内3 / 4的时间压力，应用，和b ）时，反应性充血blanches压力适用，而第一阶段没有压疮。皮肤可能是炎热或天气较正常清凉，有一个奇怪的纹理，也许是痛苦的病人。虽然容易确定的轻皮肤患者，溃疡较深皮肤个人可能显示为色调的紫色或蓝色相比，更轻肤色。
第二阶段是破坏表皮延伸到，但没有深度超过，真皮。在这个阶段，溃疡可称为泡罩或擦伤。
第三阶段涉及到全层皮肤和可扩展到皮下组织层。这层有一个相对贫穷的血液供应，并可能难以癒合。在这一阶段，可能有破坏的损害，使创面远远大于它可能似乎表面上。
第四阶段的压力ulcerStage四是最深的，延伸到肌肉，肌腱，甚至骨骼。
Unstageable褥疮佈满死细胞，或焦痂和伤口渗出液，所以深度不能确定。
