Dabir Alternating Air Pressure (AP) Support Surface:
Comfort & Patient Support
Support Pressure & Duration of Pressure
Evidence indicates pressure and injury prevalence at anatomical sites are not directly correlated. This suggests the strong influence of other factors associated with pressure injuries (ulcers) and their formation. Duration of pressure is the critical variable to control, and Dabir surfaces optimize the time of stress by providing periodic tissue offloading to promote healthy tissue perfusion.
Skin Shear Management
The nodal geometry of the surface is designed to be small in scale. Minimizing the distance between areas of patient contact with the surface reduces skin stretch during alternating support immersion. This addresses the number one factor associated with pressure injury formation: SKIN SHEAR.

Immersion into a support surface 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 while maintaining the benefits of pressure redistribution as the base surgical pad envelops the patient or supports the mattress.
Immersion becomes problematic when parts of the patient’s skin sink into significant gaps between alternating support areas. This can lead to excess skin stretch, potential skin shear, and pressure injury. This effect is exacerbated by moisture in the form of sweat.
If the skeletal structure supporting the patient’s weight sinks into these significant gaps, skin loading goes from a compression state to a hammock-type tension state or shear condition. This accelerates the rate of pressure injury formation.
Dabir Alternating Nodal Support
Dabir surfaces achieve alternating support/relief utilizing independent rows of small comfort nodes that promote interstitial blood flow between contact areas. In addition, the Dabir electronic controller provides adjustable cycle speed and firmness control to maximize patient comfort and enhance tissue re-perfusion between alternating support cycles.
