Skin Shear Management

Dabir nodal support geometry is engineered to be smaller in scale as compared to competing alternating support solutions. By shortening the distance between areas in contact skin stretch during alternating support immersion is reduced, thus addressing the number one factor associated with pressure injury formation: SKIN SHEAR.


Immersion into a support surface is good as it reduces the support pressure acting on the skin by distributing the patient's weight over a larger area of contact. Dabir surfaces take advantage of this principle by protecting the patient's skin during initial immersion, yet maintains the benefits of pressure redistribution as the patient is enveloped by the base support mattress or surgical pad.

Unless sliding occurs, immersion into large gaps between alternating areas of support can lead to excess skin stretch and potential skin shear, an effect that is worsened in the presence of moisture (sweat) and its correspondingly higher coefficient of friction. To compound matters, if the skeletal structure supporting the patient's weight is allowed to sink into these wells, skin loading migrates from compressive to a hammock type tension state or shear condition, accelerating the rate of injury formation. As such, the Dabir surface is engineered with small nodal geometry to minimize this effect and preserve healthy tissue perfusion.
