According to the Biomedical and technical aids unit of the University of Toledo in Spain, exposure to external factors that the skin must undergo when in contact with an object for a long time raises the presence of phenomena of friction, pressure, shear, heat or humidity causing tissue damage that ends up becoming pressure sores or ulcers, which prevent proper blood circulation and tissue nutrition, hence the definition of a pathology of ischemic origin that directly affects the skin and its adjacent tissues is supported ; This pathology stipulates not only physical but psychological changes due to the conditions that I bring. Maintaining a sitting posture for prolonged periods of time is one of the main reasons why pressure ulcers can develop.To generate prevention in the formation of these sores, manual techniques are used that consist of the location and movement of the patient according to the clock hands under certain times, in addition to ensuring external conditions that favor the skin and its adjacent tissues; Another of the techniques is based on the use of elements designed from the movement of air and manual regulation of pressures as required by the patient, this element is known as an anti-decubitus cushion or mattress, where despite the importance in its Prevention exercise are not highly used for different situations, among which are costs, conditions of use (hygiene and constant monitoring) and difficult access at the location of pressures manually.
