Understanding Shear Forces in Patient Care
When a patient moves, even slightly, their skin can experience shear forces—a hidden but significant cause of pressure injuries. In high-risk areas like bony prominences, shear can lead to discomfort, tissue damage, and complications over time. The right positioning solutions don’t just provide comfort; they actively protect patients from
these forces.
In this post, we’ll explore how the Evolution Patient Positioner is designed to relieve shear forces, ensuring patient safety by keeping them securely positioned while minimizing movement-related friction.
Requirement: Relieve Shear Forces Caused by Patient Movement
✅ How the Evolution Patient Positioner Works:
The positioner closes in around the patient’s body as weight is applied, creating a cupping motion that prevents side-to-side movement. By keeping the patient securely in place, it eliminates the risk of shear motion on bony prominences and other vulnerable areas.
Why This Matters: The Rationale
🔹 Shear pressure injuries occur when the skin remains in place while deeper tissues shift, leading to tissue damage.
🔹 The ideal surface moves with the patient, absorbing shear pressures rather than transferring them to the skin.
🔹 By holding onto the patient rather than slipping against them, the Evolution Patient Positioner minimizes shear-related friction and pressure.
Visualizing the Difference
