The principles <strong>and</strong> process ensure that agreedoutcome measures are achieved. <strong>Pressure</strong> ulcer monitoring must include:• Monthly incidence reports both at clinical <strong>and</strong> organisational level• Monthly clinical pressure ulcer prevalence audits5. DefinitionsBlanching Hyperaemia - reddened areas turn white following application of fingerpressure; this indicates that the microcirculation is intact.Epithelialisation - regeneration of the epidermis across the wound surface.Erythema - redness of the skin surface caused by vasodilation.Eschar - brown or black necrotic tissue.Exudate - any fluid that has exuded out of a tissue or its capillaries because of aninjury or inflammation <strong>and</strong> is high in protein <strong>and</strong> white cells.Friction - a force created by two surfaces in contact moving across each other.Granulation - healing tissue composed of newly formed capillaries <strong>and</strong> fibroblasts.Incidence - the frequency of occurrence of any event or condition over a period oftime <strong>and</strong> in relation to the population in which it occurs, as an incidence of a disease.Ischaemia - deficiency of blood, due to obstruction or constriction of a blood vessel.Necrosis - death of tissue.Non-blanching Hyperaemia - persistent redness when finger pressure is applied toan area of reactive hyperaemia indicating disruption to the microcirculation.<strong>Pressure</strong> - a perpendicular load or force.<strong>Pressure</strong> Reducing Support Surfaces - support surfaces that maintain tissueinterface.<strong>Pressure</strong> Support Surfaces - support surfaces that maintain tissue interface pressure<strong>Pressure</strong> <strong>Ulcer</strong> - an area of localised tissue damage caused by unrelieved pressure,friction or shear. <strong>Pressure</strong> ulcers occur most commonly on the sacrum <strong>and</strong> heel butcan develop anywhere on the body including the coccyx, occiput, clavicle, ear <strong>and</strong>nose. Other terms for a pressure ulcer are pressure sore, bedsore <strong>and</strong> decubitus ulcer.Prevalence - the number of existing cases of a particular disease or condition in agiven population at a designated time.Reactive Hyperaemia - a normal compensatory mechanism following an episode ofreduced skin perfusion to the tissues as a result of pressure. Relief of pressure resultsin reddening of skin caused by blood returning back into ischaemic tissues.Compliance with this policy directive is m<strong>and</strong>atory Page 11 of 20
