Dr. Lee Ruotsi and Dr. Amit Gefen explain how dressings reduce shear, protect tissue, and improve pressure injury prevention strategies.
In this episode, Dr. Lee Ruotsi speaks with Dr. Amit Gefen, Professor of Biomedical Engineering at Tel Aviv University and a leading expert in tissue mechanobiology, about how prophylactic dressings help prevent pressure injuries.
Dr. Gefen explains how pressure, shear, and friction act on soft tissue, and why these forces work together to cause damage beneath the skin. He also describes what happens at the cellular level when tissue is exposed to sustained load, and how injury can develop even when the surface still looks intact.
The discussion covers how dressings help reduce shear, especially over areas like the sacrum and heels. Dr. Gefen outlines how multilayer designs absorb movement and limit the amount of force that reaches the tissue. He also touches on heat, moisture, and how microclimate affects skin condition and friction. The episode highlights why clinicians should look for product-specific evidence when choosing dressings, as performance can vary across different designs.
