Study: Hyperoxia Alters Microcirculation in Healthy Volunteers

2015 19 Jan

Hyperoxia may induce vasoconstriction and alter endothelial function. However, recent data suggest a potential therapeutic role of normobaric hyperoxia (NH) in sepsis and cerebral ischaemia. In this study, researchers evaluated the effects of NH on the microcirculation in 40 healthy adult volunteers using side-stream dark field (SDF) video-microscopy... Read more
