摘要: Patients can show arterial pressure and cardiac index within the normal range still be in circulatory shock if oxygen metabolic demand is increased or blood flow distribution altered.Lactate produced anaerobic environment to preserve cellular integrity physicians use its concentration value as a reliable marker of tissue hypoxia energy failure.The authors review recent literature on importance mixed venous saturation (SvO(2)) an early sign inadequate DO(2) that precede lactate production.
