What is tissue viability about?
Tissue Viability is about the maintenance of Tissue Viability is about the maintenance of skin integrity. Also the management of skin integrity.

Scottish Adapted EPUAP Grading Tool
(NATVNS –Scotland)
Non blanchable erythema of intact skin.
Discolouration of the skin, warmth, oedema, induration or hardness may also be used as indicators, particularly on individuals with darker skin1
Partial thickness skin loss involving epidermis, dermis, or both. The ulcer is superficial and presents clinically as an abrasion or blister.1
Full thickness skin loss involving damage to or necrosis of subcutaneous tissue that may extend down to, but not through underlying fascia.1
Extensive destruction, tissue necrosis, or damage to muscle, bone, or supporting structures with or without full thickness skin loss.1

moving and handling techniques
The 30 degree tilt Recumbent position
Advantages of the 30° tilt• The patients weight is spread over a larger area, this will
reduce the risk of pressure damage over the hot spots
• The patient lies on a 30 tilt so they have a better view of their surroundings and may find it easier to eat and drink.
• Reduces risk of tissue damage from shear and friction (usually occurs when a patient slips down the bed)
• As this position only involves tilting (not lifting) carers will find it easier to perform and greatly reduces the risk of back injuries
