Pressure injuries can develop within 24 hours of the initial pressure but may take as long as a week to present themselves. The localized damage in a pressure injury is the result of compression of soft tissue that interferes with the tissue’s blood supply, leading to vascular insufficiency, tissue anoxia, and cell death. The tolerance of soft tissue for pressure and shear may also be affected by microclimate, nutrition, perfusion, comorbidities, and condition of the soft tissue. The injury occurs as a result of intense and/or prolonged pressure or pressure in combination with shear. The injury can present as intact skin or an open ulcer and may be painful. The National Pressure Injury Advisory Panel (NPIAP, 2016a) definition states:Ī pressure injury is localized damage to the skin and underlying soft tissue usually over a bony prominence or related to a medical or other device. Over the years, the definition of a pressure injury has been refined as medical knowledge and understanding of the disease process has advanced, along with improvements in treatment approaches and imaging technology. Pressure injury is not new, and the terminology to describe it has varied over time: There are many factors that contribute to the development of a pressure injury and whether or not it will heal, but the biggest factor in all of these is pressure. A pressure injury can also result from a combination of pressure and shear. Wounds involving the skin are a frequent occurrence in all age groups.Ī pressure injury is a wound unlike any other in that its cause is not surgery or trauma but death of the skin and underlying tissues from ischemia due to intense and/or prolonged pressure. Similar to any other organ in the body, the human skin is susceptible to disease and injury. Human skin serves many vital functions, the most critical of these being to provide a barrier between the external environment and the internal environment of the body. The skin is the largest organ in the human body-and essential to life and well-being.
