Today, decubitus ulcers are the 3ed highest costly disease after cardiovascular, cancers and respiratory diseases. The death rates from decubitus ulcers are two to six times as much as from common problems, with sixty thousand deaths annually due to the complication of decubitus ulcers. Decubitusulcers are one of the types of an ulcer that breaks down the skin and continuous pressor over the area of the skin for a certain period causing tissue ischaemia, insufficient supplies of nutrition and oxygen to the tissues lead to tissue necrosis. The skin is able of sustaining pressure on the arterial side of around 32 - 34mmHg for only a small duration of time. External pressure must exceed the arterial capillary pressure (32 mmHg) to impede blood flow and must be greater than the venous capillary closing pressure (8 to 12 mmHg) to impair the return of venous blood. The occluding the blood supply, tissue distortion also damage the lymphatic flow, which leads to the stagnated of body waste products, material and enzymes in the damaged tissue. Due to distortion of tissues, soft tissues are compressed and sheared between the skeleton and support, such as a bed, chair when the person is sitting, lying, because something is pressing into the body, such as a shoe, a prosthesis, a surgical appliance and clothing elastic. Some health conditions influence blood supply and capillary perfusion, such as diabetes, the paralysed patient with a spinal injury loses sensation. In Indian, the prevalence of pressure ulcers in hospitalized patients has been reported to be 4.94% and 22% in nursing - home populations They often result in significant pain and distress, lead to other complications.
