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.

Healthcare-Associated Infections and the Hospital Bed.

Objective: Bedframes are a potential source of bacterial contamination, fomites, and healthcare-associated infections for patients with active skin wounds and other underlying conditions. Bedframes also differ in their design, materials, texture, and ease of disassembly for cleaning. In this study, the authors evaluated five hospital bedframes in terms of retained soil and ease of cleaning as rated by volunteers.
