A 55-year-old man on ICU has septic shock. His central venous blood gas shows ScvO2 of 82% and lactate is 6 mmol/L. What mechanism explains the high ScvO2 with elevated lactate?AThe SvO2 is falsely elevatedBCytopathic hypoxia - mitochondrial dysfunction caused by sepsis-induced inflammatory mediators impairs cellular oxygen utilisation; oxygen returns unused in venous blood (high SvO2), while anaerobic metabolism generates lactate despite adequate global oxygen deliveryCCarbon monoxide poisoningDCytopathic hypoxia is the same as hypovolaemic shockEHigh SvO2 always indicates adequate tissue oxygenationCheck my answer
