2022年9月26日 · 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 arterial blood gas; however, there are other methods, such as peripheral venous, central venous, or mixed venous sampling.

2024年5月8日 · Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg, or 4.7 to 6.0 kPa. The PaCO2 level is the respiratory component of the ABG. It is a measurement of carbon dioxide (CO2) in the blood and is …

2023年10月7日 · PCO2为血二氧化碳分压，临床上一般指动脉血二氧化碳分压(PaCO2)，较为有意义，正常值为35-45mmHg(4.7-6.0kPa)，平均值为40mmHg(5.33kPa)。 PaCO2是正常溶解在动脉血中的二氧化碳分子产生的张力，一般每1

血二氧化碳分压（Partial Pressure of Carbon Dioxide，PCO2）指溶解在血液中的二氧化碳分子产生的压力，又称二氧化碳张力。 动脉血中的二氧化碳分压称“动脉血二氧化碳分压”，记作PaCO2；静脉血中的二氧化碳分压称“静脉血二氧化碳分压”，记作PvCO2。

2020年10月9日 · PaCO2 is the partial pressure of carbon dioxide in arterial blood. This is the amount of strong acid which would need to be added or subtracted from a substance in order to return the pH to normal (7.40). A value outside of the normal range (-2 to +2 mEq/L) suggests a metabolic cause for the acidosis or alkalosis.

pCO2, pCO2, or is the partial pressure of carbon dioxide (CO 2), often used in reference to blood but also used in meteorology, climate science, oceanography, and limnology to describe the fractional pressure of CO 2 as a function of its concentration in gas or dissolved phases.

2021年5月5日 · 因此呼吸系统很少将 pCO2 保持在 7.5 kPa 以上。 如果 pCO 2 超过这一数值，则说明存在混合型酸碱平衡紊乱，也即代谢性碱中毒合并呼吸性酸中毒，而不是代偿性代谢性碱中毒。

2019年10月4日 · pCO2增高，常见于阻塞性肺气肿、慢性支气管炎、支气管哮喘、充血性心力衰竭、呼吸中枢疾患，吗啡、巴比妥类中毒、大脑器质性疾患。 pCO2降低： 因呼吸浅快，pCO2因CO2排出增多而降低。

2022年9月26日 · 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 arterial blood gas; however, there are other methods, such as peripheral venous, central venous, or mixed venous sampling.

2025年1月4日 · The normal Pco2 reference range varies slightly depending on the laboratory and the specific population being studied. However, in general, the accepted range for arterial blood is between 35 mmHg and 45 mmHg (4.7 kPa to 6.0 kPa). This range may be slightly higher for venous blood, typically between 40 mmHg and 50 mmHg (5.3 kPa to 6.7 kPa).
