There are two main reasons for the development of pressure ulcers.
Firstly external pressure that squashes blood vessels. Pressure on the bony prominences of the body in particular can result in obstruction of the blood vessels, which deprives tissues of oxygen and nutrients, causing ischemia, hypoxia (not enough oxygen for the cells), edema, inflammation, and ultimately necrosis and ulcer formation. The usual places for pressure ulcers to occur are the coccyx, trochanter and the heel.
The second main reason is friction and shear forces which injure or tear the blood vessels just under the skin. Friction usually occurs when two surfaces rub together for example the elbow and a bed sheet or wheelchair arm rest.
The solution: DermaSavers amazing micro filament technology absorbs the shear forces before any damage can be done. An innovative range of skin protection and skin protectors products from the manufacturers of the HipSaver soft hip protector. DermaSavers protect fragile skin from sustaining damage caused by friction, rubbing, abrasion and pressure that could lead to skin breakdowns, tears and splits. DermaSaver can also help to heal existing skin tears, splits and lacerations without the restriction of bandages and dressings.
