Decubitus is a chronic wound that occurs due to long-term pressure on the surface and thus damages the skin and subcutaneous tissue. Decubital ulcers due to reduced circulation and lack of nutrients at the pressure point can occur after 12 hours, so it is recommended to change the position and turn the patient every two hours. The nurse/technician recognizes the signs of risk immediately upon receiving the patient and, based on the skin inspection and application of the scales, further plans the care and prevention of pressure ulcers. Prevention requires the education and expertise of the medical team in order to provide adequate care for the patient and his family. It is important to cover a person's physical and mental health in its entirety, because the occurrence of decubitus wounds and chronic wounds themselves ultimately impairs the quality of life and the perception of one's own body. In the treatment of decubitus, dressings are most often used, which are best suited to the degree of decubitus, so that the wound can heal as quickly as possible. In addition to dressings, there is also surgical treatment, which removes necrotic tissue and thus contributes to better wound healing. Treatment of decubitus should not ignore other possible diagnoses that the patient has, and in addition to the prevention and treatment of decubitus, it is necessary to treat the underlying disease. At the end of the final paper, the results of a short research on the knowledge of medical professionals about decubital ulcers are listed.
