What are the stages of pressure ulcers?

Pressure sores are often referred to as bedsores in clinical practice. As they are more common in patients who lie in bed for a long time, they show some manual factors due to poor local blood circulation. This initial factor of poor local blood circulation will slowly enter into inflammation and finally show local ulcers. Even this ulcer will become deeper and deeper, showing that it has been upgraded to the lower layer of the dermis, resulting in exposure of muscles, tendons and even bones. We generally stage clinically. I just mentioned that this erythema can be manifested in the first stage. The second stage is the infiltration stage of inflammation. In the second stage, we say that it is mainly the absence of part of the dermis, but it has not reached the deeper level. The third stage is the superficial ulcer stage. The fourth stage is the deep ulcer stage, or the deep necrotic ulcer stage. The whole ulcer stage shows the absence of all skin layers, but without exposing the tendon muscles. If the fourth stage of necrotic ulcer stage is reached, it will not only show the absence of all skin tissues, but also with the exposure of deep muscle tendons and even bones. Pressure sores occur in patients who are bedridden for a long time. once pressure sores are present and accompanied by systemic conditions, this gradually debilitating condition often indicates that the patient's condition gradually becomes localized to the whole body, and a failure begins.
