血气分析指标中的二氧化碳分压越高，死亡率也相应升高；
The higher partial pressure of carbon dioxide(Pco2)in BGAI, the higher death rate;
两组之间无明显的血液动力学或呼气末二氧化碳分压的差别。
There were no significant differences in hemodynamics and end-tidal CO2 partial pressure between the two groups.
是呼吸中枢对血液中二氧化碳分压变化的反射性刺激发生障码。
Is the Respiratory center the carbon dioxide differential pressure change reflective stimulation occurs to the blood in bonds the code.
目的：探讨慢性阻塞性肺病的合并症及二氧化碳分压与生命质量的相关性，以全面了解COPD患者的病情及预后。
Objective: To investigate the complications and relationship of the quality of life with PaCO2 in patients with COPD.
因此，二氧化碳监测仪提供了一种连续的非侵袭性的反应动脉血二氧化碳分压的方法，二氧化碳分压直接由肺泡通气决定。
Hence capnometry offers a continuous, non-invasive way to reflect the partial pressure of carbon dioxide in arterial blood, which is directly determined by alveolar ventilation.
研究者指出，和更差的生存率相关的是年龄大于70岁、存在并发的呼吸系统疾病、动脉血氧分压降低、动脉血二氧化碳分压降低。
Other factors associated with worse survival were being older than 70 years, the presence of a concomitant respiratory disease, low PaO2, and low PaCO2, the researchers note.
