Carbon dioxide (CO2) is an acidic gas; the amount of CO2in blood is largely controlled by the rate and depth of breathing or ventilation.pCO2is the partial pressure of CO2in blood. It is a measure of the pressure exerted by that small portion (~5 %) of total CO2that remains in the...

As the level of carbon dioxide increases, the level of carbonic acid also increases. Because Pco2 and carbonic acid values are higher in venous blood than in arterial blood, venous blood is slightly more acidic (pH, 7.38) than arterial blood (pH, 7.40). Third, a majority of carbon dioxide...
We measured partial pressure of CO2 (pCO2) in blood samples withdrawn from the venous line of the extracorporeal circuit during BD and subsequently during AFB in 22 stable chronic hemodialysis outpatients. The amount of CO2 coming back to the patient's bloodstream is higher in BD (59.1±4.0mmol...
(PaCO2of 47.1 vs. 39.7 mm Hg, respectively) showed no difference in mortality despite worsened health in the hypercapnic patients; i.e., these patients had a higher body mass index (BMI) and higher number of venous thromboembolic events, chronic obstructive pulmonary disease (COPD) or ARDS [...
hyperbaric therapy [17]. On the other hand, high concentrations of oxygen raise venous pO2which reduces the solubility of carbon dioxide in the blood. With no changes in the metabolic conditions, this in turn causes pCO2in the venous blood to rise. Due to this so-called Haldane effect, an...
Extracorporeal (EC) carbon dioxide (CO2) removal (ECCO2R) may be a powerful alternative to ventilation, possibly avoiding the need for mechanical ventilation and endotracheal intubation. We previously reported how an infusion of lactic acid before a membrane lung (ML) effectively enhances ECCO2R....
The partial pressure of carbon dioxide is 5.3 pKa in arterial blood and 6.1 kPa in mixed venous blood; therefore, arterial blood will contain about 2.5 ml per 100 ml of dissolved carbon dioxide and venous blood 3 ml per 100 ml. A cardiac output of 5 litre min−1 will carry 150 ml ...
