二氧化碳分压（PCO 2）是动脉或静脉血液中二氧化碳的量度。它通常作为肺内肺泡通气充足的标志。通常，在正常生理条件下，PCO 2的值在35至45 mmHg或4.7至6.0 kPa之间。通常，通过动脉血气进行PCO 2的测量;但是，还有其他方法，例如外周静脉、中心静脉或混合静脉采样。样品的收集和PCO 2的使用是下文进一步讨论的主题。
The partial pressure of carbon dioxide (PCO2) is the measure of carbon dioxide within arterial or venous blood. It often serves as a marker of sufficient alveolar ventilation within the lungs. Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg, or 4.7 to 6.0 kPa. Typically the measurement of PCO2 is performed via an arterial blood gas; however, there are other methods such as peripheral venous, central venous, or mixed venous sampling. The collection of samples and the use of PCO2 is a topic of further discussion below.
