Effects on tissue oxygenation in the gluteal region with a smart pressure redistribution wheelchair cushion compared to a pressure relief manoeuvre.

Objective: The study examines the effects of the air-bladder offloading mode of a smart pressure redistribution wheelchair cushion on tissue oxygenation in the gluteal tissue of non-disabled participants. The hypothesis is that the cushion's offloading mode, which involves sequentially deflating its five air-bladders one at a time for a specific duration, would improve tissue oxygenation during sitting.

Methods: Two procedures were conducted.

Using high-resolution imaging to study the impact of the Kalogon wheelchair cushion on blood flow in the gluteal area.

Aim Of The Study: This study investigated how the air-bladder offloading mode of the Orbiter by Kalogon wheelchair cushion (Orbiter) affected blood flow in the gluteal region of non-disabled subjects. The hypothesis was that the cushion's offloading mode would improve blood flow, resulting in reduced reactive hyperemia when compared to the static setting, or Loaded Control (LC). Furthermore, the study proposed a technique using a high-resolution image laser speckle contrast system to measure blood flow in the gluteal area.

Use of a Shear Reduction Surface for Prehospital Transport: A Randomized Crossover Study.

Objective: To compare the effectiveness of an antishear mattress overlay (ASMO) with a standard ambulance stretcher surface in reducing pressure and shear and increasing patient comfort.

Methods: In this randomized, crossover design, adults in three body mass index categories served as their own controls. Pressure/shear sensors were applied to the sacrum, ischial tuberosity, and heel.
