HYPOXIC, PATHOGENESIS
Oxygen deficit is a determinant of postoperative morbidity and mortality [O3Besides somatic oxygen saturation, studies regarding renal oxygen saturation have been emerging as well. The kidneys are prone to hypoxic and ischemic injury, which contributes to the pathogenesis of acute kidney injury [We aimed to compare O3-derived oxygen saturation values to invasive somatic and renal reference oxygen saturation values in healthy volunteers. We hypothesized that (1) oxygen saturation values measured at the quadriceps and flank have a good agreement with invasive
