In this case we evaluated brain tissue pO2, pCO2 and pH during ischemia and arterial oxygen desaturation (hypoxia). In both situations brain pO2 decreased. During ischemia, tissue pCO2 increased while pH decreased; but both pCO2 and pH were stable during hypoxia. These results suggest that brain tissue pO2, pCO2 and pH measures provide information on tissue perfusion and oxygen availability during ischemia and hypoxia.
在这种情况下，我们评估了缺血和动脉血氧饱和度降低（缺氧）期间脑组织的氧分压（pO2）、二氧化碳分压（pCO2）和pH值。在这两种情况下，脑pO2均降低。在缺血期间，组织pCO2升高而pH值降低；但在缺氧期间，pCO2和pH值均保持稳定。这些结果表明，脑组织pO2、pCO2和pH值测量可提供有关缺血和缺氧期间组织灌注和氧供应的信息。
