How to be less invasive. Powles AC, Campbell EJ. Unless cardiac output is reduced, alveolar ventilation can be monitored without arterial blood gas analysis by estimating arterial carbon dioxide tension (PaO2) from rebreathing measurement of mixed venous carbon dioxide tension (PvCO2) (PaCO2 = 0.8 PvCO2).

They note that in some cases the PvCO2 was lower than the PaCO2. The meta-analysis had considerable heterogeneity between studies which limits the reliability of its conclusions. HCO3 Good correlation Mean difference −1.41 mmol/L (−5.8 to +5.3 mmol/L
Respiration is controlled by a section of the brain called the medulla. Lying on either side of the medulla are chemoreceptors that sense changes in the level of pCO2 in the blood. When the level of pCO2 becomes too high or too low, chemoreceptors send signals to
二酸化炭素（CO 2 ）は酸性ガスで、血液中のCO 2 量は主に呼吸の速さと深さにより制御されます。 pCO 2 は血液中のCO 2 分圧です。 これは、血漿中に気体状態で残存する総CO 2 の一部（最大5%）から導き出されます。 pCO 2 は酸塩基平衡の呼吸性因子で、肺換気量の妥当性を反映します。

O termo gasometria arterial refere-se a um tipo de exame de sangue colhido de uma artéria e que possui por objetivo a avaliação de gases (oxigênio e gás carbônico) distribuídos no sangue, do pH (se a informação for somente para avaliar o pH pode-se fazer gasometria venosa) e do equilíbrio ácido-básico.
An arterial-blood gas (ABG) test measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle,[1] but sometimes the femoral artery in the groin or another site is used. The blood can also be drawn from an arterial

4/3/1978 · It can be measured instead of the arterial carbon dioxide tension (PACO2) to follow changes in alveolar ventilation when the cardiac output is normal (PaCO2 = 0.8 PVCO2). When the cardiac output is abnormal, measurement of both PaCO2 and PvCO2 is useful
