· Bed Sores — also called pressure sores or pressure ulcers — are injuries to skin and underlying tissue resulting from prolonged pressure on the skin. Bedsores most often develop on skin that covers bony areas of the body, such as the heels, ankles, hips and tailbone.
· People most at risk of bedsores are those with a medical condition that limits their ability to change positions, requires them to use a wheelchair or confines them to a bed for a long time.
Pathophysiology of pressure ulcers
· There are four main factors implicated in the pathogenesis of pressure ulcers – pressure, shear force, friction and moisture

· Energy and protein, arginine and micronutrients (vitamins A and C and zinc) are all important in the wound healing process and current recommendations tend to focus on these particular nutrients
· Increased energy and protein intakes are typically promoted for patients with pressure ulcers, with recent recommendations by the European Pressure Ulcer Advisory Panel (EPUAP) advocating a minimum of 30-35kcal per kg body weight per day and 1-1.5g or 1.25 to 1.5 g protein per kg body weight per day
