The Difference between Friction and Shear Checklist for Factors Affecting Wound Healing Pressure Ulcer Staging Revisited: Superficial Skin Changes & Deep Pressure Ulcer Framework© 2015 Jan-Feb;42(1):47-61. doi: 10.1097/WON.0000000000000087.Int J Nurs Stud. Many times you may identify signs of shearing stresses within a wound that presents an irregular shape and undermining. Friction usually, but not always, accompanies shear. The analysis in this article suggests that friction can contribute to pressure ulcers by creating shear strain in deeper tissues, but friction does not appear to contribute to pressure ulcers While the major factor in the development of pressure injury is pressure itself shear and friction forces also play a part.When you move over a surface and remain in contact with it, the skin gets pulled along that surface. Friction injuries are often misdiagnosed as pressure ulcers. This analysis assesses the classic literature that led to the inclusion of friction as a causative factor in the development of pressure ulcers in light of more recent research on the effects of shear. Epub 2017 Mar 28. When Barbra asked her doctor what caused her wound, the doctor told her that her wound was caused by shearing and friction forces. Barbara was confused as to what caused this large wound to form since she does not remember being cut by anything. Wolters Kluwer 2018 Oct;69(10):839-847. doi: 10.1007/s00105-018-4230-6.Alderden J, Cummins MR, Pepper GA, Whitney JD, Zhang Y, Butcher R, Thomas D.J Wound Ostomy Continence Nurs. Injuries to the superficial layers of the skin caused by friction are not pressure ulcers and should not be classified or treated as such.
For the past couple weeks, there has been an ulcer wound on Barbara's lower back that has progressively gotten bigger, deeper, and more painful. Please enable it to take advantage of the complete set of features! Friction is the force of rubbing two surfaces against one another. Wolters Kluwer Name must be less than 100 characters When there is loss of the top skin layer, there is also a breach in the barrier against infection.
There are several strategies to reduce shear and friction forces: This is due to friction. 2017 Sep/Oct;44(5):420-428. doi: 10.1097/WON.0000000000000349.Alderden J, Rondinelli J, Pepper G, Cummins M, Whitney J.Int J Nurs Stud. This inflammation can lead to deeper injury or could be the initial damage needed to start pressure ulcer formation.

Barbara is an 83-year-old woman who lives in a nursing home and is bedridden. COVID-19 is an emerging, rapidly evolving situation. Epub 2011 Aug 12.Cutan Ocul Toxicol. This analysis assesses the classic literature that led to t … There may even be evidence of excoriation and blistering on areas in contact with support surfaces. You can feel this ‘drag’ effect if you run your hand over something.Shear causes stretching and tearing of blood vessels which reduces blood flow, increases blood pooling and can lead to cell damage.Shearing stops or reduces blood flow more easily than pressure alone (for example, it is easier to cut off flow in a water hose by bending than by pinching it).Although shear and friction causes tissue damage slightly differently to pressure, the damage produced is the same as with pressure.Importantly, it is difficult to create pressure without shear, and shear without pressure, so the two usually go hand-in-hand.For information on how pressure leads to pressure injury, see our article As well as being a key element of making shear force, friction between the skin and the stationary surfaces such as bed clothes can result in the loss of the top layer of the skin (the stratum corneum).Think about repeatedly rubbing your skin against a surface – after a time, the skin would start to become red and sore.
The reason for the misdiagnosis may be a misinterpretation of classic pressure ulcer literature that reported friction increased the susceptibility of the skin to pressure damage. The analysis in this article suggests that friction can contribute to pressure ulcers by creating shear strain in deeper tissues, but friction does not appear to contribute to pressure ulcers in the superficial layers of the skin.
