Development of the equation for position change interval to prevent the pressure ulcer using the animal model with weak tissue tolerance

Pressure ulcers are localized areas of tissue breakdown in skin and/or underlying tissues. One of the preventative cares is repositioning at least every 2 hours. Researchers investigated the interval for the repositioning using the finite-element model and the animal model with malnutrition. Based on the results, malnutrition delayed the wound healing and deep tissue damage was predominant. Further study is needed to develop the equation for position change interval for the at risk people with weak tissue tolerance.
