Decubitus or decubitus ulcer is damage to the skin that is caused by constantly present mechanical pressures on a certain part of the skin of the body. Due to the constant pressure, there is less blood supply to the tissues. In severe cases, there may be a complete disruption of supply, leading to tissue or deeper structures dying. In addition to being a major health problem, pressure ulcers are also a financial problem of the patient, the institution in which the patient is housed, his family of the wider community. As such a patient is treated well, multidisciplinary and holistic care is needed.
