“…One important factor in reducing the high pressure on tissue interfaces is friction coefficient, where the difference in friction coefficient gives a significant effect on the pressure obtained [13,[16][17][18]. This condition is parallel with studies by previous researchers who stated that risk of pressure sores on patients could be reduced by considering the condition of friction and shear stress on tissue interfaces [19].…”

“…The friction coefficients between the contact interfaces of tissue and pelvic binder were determined based on two different conditions i.e. 0.3 in dry skin and 0.8 in wet skin [19]. This factor was taken into account because there is a correlation between mechanical behaviour and damaged tissue, in which tissue damage can be avoided by reducing friction and shear force on tissue interactions [19].…”

Pelvic circumferential compression is a device used to reduce injury which inadvertently, cause soft tissue damage. When force is applied excessively to the pelvic binder, tissue is damaged due to prolonged high pressure. Therefore, effect from this interaction between tissue and pelvic binder is an important factor to avoid pressure sores due to human tissue damage. The aim of this study is to investigate the effects of human tissue interaction due to compression of the pelvic binder using a finite element modelling approach. A three-dimensional human pelvic model was developed to simulate pressure distribution on tissue interfaces. The applied loads with two different conditions -dry and wet skin were applied on both tips of the pelvic strap during binder-tissue interaction. The compression load of the pelvic binder was estimated on a pelvic strap in order to reduce pelvic fracture. The compression load was varied substantially between locations as well as between skin conditions. There were two straps on the pelvis. For pelvic strap 1, the pressure on the sacrum and ilium was higher than the pressure measured on pelvic strap 2 while pressure on the anterior area was the same for both pelvic straps. Analysis results showed that the pressure which developed between both tissue and pelvic binder exceeded the recommended pressure i.e. ≥ 9.3 kPa at tissue interfaces. When pressure on tissue interfaces is not controlled, this condition can lead to tissue damage due to prolonged periods of time. Hence, to avoid tissue damage to the pelvic binder a cushion must be introduced to reduce the effect of tissue reaction from the prehospital device. Subsequently, tissue and pelvic binder interaction simulation results were compared with experimental data for validation in the model developed.

“…6 However, the evidence to apply repositioning to prevent pressure ulcers is low and we still do not know if particular positions or frequencies of repositioning reduce pressure ulcer development. 34 As the authors of a Cochrane review (April 2014) advice: further research about the best way of using repositioning is necessary. 34 Not only the pressure redistributing surface is important; as we have seen, also the humidity between the blankets or mattress cover and the skin of the resident may play an important role in the risk of developing a PU.…”

General introduction 10Pressure and shear are the most mentioned direct causes of a pressure ulcer. 7,8,9,10 Pressure is defined as the amount of force/load applied perpendicular per unit area of application. 10 A force applied over a small area will produce a greater pressure than the same force over a larger area. Two aspects of pressure are important: intensity and duration. The intensity is defined as the amount of external pressure on the skin and the deeper tissue layers. Duration is the time that a certain pressure is exposed to a surface. A short period of high pressure or a longer period of a lower pressure may both result in a PU.Shear is often used to abbreviate the terms shear stress and shear force. Friction is no longer mentioned in the description of PU development in the last NPUAP/EPUAP/PPPIA guideline, but there is a close association with shear. Friction is defined as the force that resists the relative motion of two adjacent objects, like skin and support interface. Often friction potentiates shear stress. 12Prevention of pressure ulcers in nursing homes, a big challengeIf pressure and shear are applied to the skin, particularly over a bony prominence, it causes changes of the skin and the underlying tissue. This may result in tissue distortion, compression of blood vessels, stretching and narrowing of the capillary beds, disturbance of the cell metabolism and even cell death. A sufficient high level of shear stresses for a period of 4 hours will result in muscle death. The skin can resist the same type of stress for more than 12 hours. 12 This is one of the reasons why PUs may already have developed before skin breakdown is visible. Other Contributing factorsThe development of a PU cannot be fully explained by the effects of pressure and shear stress only. Another...
