静脉-动脉二氧化碳分压差/动脉-静脉氧含量差[P(v-a)CO2/C(a-v)O2 ratio]通过计算氧的消耗量和二氧化碳的生成量的比率获得,其本质是反映机体呼吸商。在无氧代谢时只有CO2的产生,却无O2的消耗,此时呼吸商趋向无限大。因此,当机体存在无氧代谢时,可出现P(v-a)CO2/C(a-v)O2 ratio增高。近来,应用P(v-a)CO2/C(a-v)O2 ratio作为识别机体是否存在无氧代谢的指标在休克复苏中受到广泛关注。

the P(v-a)CO2/C(a-v)O2 ratio was calculated from the ratio of the CO2 production and O2 consumption, which reflect the respiratory quotient. The respiratory quotient would be infinite in the case of the anaerobic metabolism during which only CO2 was produced without the consumption of O2. Recently, attention is paid to use the P(v-a)CO2/C(a-v)O2 ratio to detect anaerobic metabolism in the resuscitation of the circulatory shock.
