Near infrared spectroscopy during stagnant ischemia estimates central venous oxygen saturation and mixed venous oxygen saturation discrepancy in patients with severe left heart failure and additional sepsis/septic shock
... Most authors attribute this pattern to changes in the dis- tribution of cardiac output that occur in periods of hemo- dynamic instability. In shock states, blood flow to the splanchnic and renal circulations falls, while ...
