These bed sores, which result from prolonged pressure, are also called “decubitus ulcers”, “pressure sores,” and “pressure ulcers .”  How Bed Sores DevelopBed sores are a localized area of tissue injury that develops when soft tissue is compressed between a bony prominence and an external surface for a prolonged period of time.  The external surface may be a mattress, a chair or wheelchair, or even other parts of the body.  The soft tissues of the body, such as skin and muscle, depend upon blood vessels to carry nutrients to the tissues, and to remove waste products.  Bed sores result when prolonged pressure prevents sufficient blood flow to supply the tissues with nutrients.  The resulting bed sore represents the death of the involved soft tissues.  Bed sores can result from one period of sustained pressure; however, most bed sores probably occur as a result of repeated incidents of blood flow interruption without adequate time for recovery.  In fact, low pressure endured for long periods of time is believed to be more significant in producing pressure ulcers than higher pressure for shorter durations.Most CommonAreasIt is important to note that bed sores do not always result from being in bed as the name would imply.Some of the most severe bed sores can also result from sitting for a prolonged period of time. Thus, the location of the bed sores can depend upon the position of the patient.  For individuals who are bed-bound, the sores are most likely to form on or around the heels, the hip-bone, and the lower back or tailbone.  Pressure ulcers may also develop in a variety of other areas, including the spine, ankles, knees shoulders, and head, depending upon the position of the patient. Risk Factors Pressure sores are more likely to develop persons who are at higher risk due to one or more risk factors.  A number of risk factors have been identified which put individuals at higher risk.Once a person is identified as being at increased risk for pressure sores, measures should be undertaken to reduce or eliminate those risks.  Thus, healthcare providers must be aware of these risk factors when caring for patients in order to prevent the unnecessary development of pressure sores.  While risk factors may vary depending upon the particular circumstances, the following represents a list of the most common:
1.  Confinement to bed, chair, or wheelchair.   Persons confined 
to beds, chairs, or wheelchairs who are 
unable to move themselves, can develop pressure-induced injuries in 
as little as 1-2 hours if the pressure is not relieved;
2.  Inability to change 
positions without
