A research article entitled "Effects of positioning and vibration of car seats on body pressure distribution and blood flow: A fundamental study for preventing pressure injuries during vehicle evacuation," authored by a research group from the Department of Adult Nursing, Faculty of Nursing, Ishikawa Prefectural Nursing University, Ishikawa Prefectural Nursing University (corresponding author: Professor Takeo Minematsu; first author: Nana Nuka), has been published in the Journal of Japanese Society of Wound, Ostomy and Continence Management, Volume 30, Issue 1, pp. 1-11.

This study investigated methods of preventing pressure injuries during vehicle evacuation in disasters. Specifically, it examined how positioning using towels and a blanket affected body pressure distribution in a passenger car seat, and how vibration from a cushion equipped with a vibration device affected blood flow.

For the observation and analysis of capillary blood flow, the study used the capillary scope (USB) GOKO Bscan-ZD, software for advanced image analysis and measurement GOKO Measure Plus, and software for velocity measurement GOKO-VIP.

Capillary videos recorded with the GOKO Bscan-ZD were analyzed using GOKO-VIP to quantitatively evaluate capillary blood flow velocity and the proportion of vessels showing detectable blood flow before and after vibration. By separately assessing the venous system and microcirculation at the capillary level, the researchers conducted a multifaceted and objective evaluation of the effects of vibration on blood flow.
