WebA high arterial PaO 2 during administration of 100% oxygen can produce abnormally high PcvO 2 and ScvO 2 values. Rarely, a high ScvO 2 reading may indicate failure of the cells to extract. This could occur in end stage multiorgan failure or with cell toxins such as cyanide (e.g., in house fires or nitrorusside toxicity).These scenarios would be ... WebSep 12, 2015 · The high pO2 values are strictly representative of blood emerging from the ECMO pump. Pulsatility is absent during most of the time at high ECMO blood flow. Once the ECMO blood flow is reduced during weaning, the lungs receive more blood flow, pulsatility returns and the arterial pO2 reacts appropriately to the oxygen challenge.
