Abstract Objective: The mixed venous-arterial (v-a) pCO2 difference has been shown to be inversely correlated with the cardiac index (CI). A central venous pCO2, which is easier to obtain, may provide similar information. The purpose of this study was to examine the correlation between the central venous-arterial pCO2 difference and CI. Design: Prospective, cohort study. Setting: Intensive care unit of an urban tertiary care hospital. Patients and participants: Eighty-three consecutive… 
Relationship Analysis of Central Venous-to-arterial Carbon Dioxide Difference and Cardiac Index for Septic Shock
To analyze the relationship of the central venous-to-arterial carbon dioxide difference (p(cv-a)CO2) and cardiac index (CI) in patients with septic shock, an observational study was conducted in
Correlation between Central Venous - Arterial Carbon Dioxide Tension Gradient and Oxygen Delivery Changes Following Fluid Therapy
TLDR
CVA-CO2 gradient and DO2 changes were inversely and significantly correlated in patients receiving fluid therapy following coronary surgery, and could be used as an indicator to guide volume loading and to assess its effect on DO2.
Measurement of central and mixed venous-to-arterial carbon dioxide differences in cardiac surgery patients
TLDR
In cardiac surgery patients p(cv-a)CO2 cannot be used as an estimate of p(va) CO2 with acceptable accuracy, and there is no evidence that measurements of p-v-a or p(v- a)CO 2 could help diagnose global or regional tissue hypoxia in this patient group.
Correlation of central venous–arterial and mixed venous–arterial carbon dioxide tension gradient with cardiac output during neurosurgical procedures in the sitting position
TLDR
It seems that venous–arterial pCO2 values obtained from mixed and central venous circulations can be reliably interchanged in estimating CI in patients undergoing neurosurgical procedures in the sitting position.
Use of venous-to-arterial carbon dioxide tension difference to guide resuscitation therapy in septic shock.
TLDR
Experimental and clinical studies support the evidence that P (v-a) CO2 cannot serve as an indicator of tissue hypoxia, and should be regarded as a indicator of the adequacy of venous blood to wash out the total CO2 generated by the peripheral tissues.
Central venous-arterial pCO2 difference as a tool in resuscitation of septic patients
TLDR
The likelihood of a bad outcome seems to be enhanced when a high pCO2 gap persists after 24 h of therapy, and the clinical utility of central venous p CO2 values is of potential interest in determining the venous-arterial pCO1 difference.
Hemodynamic management of cardiovascular failure by using PCO2 venous-arterial difference
TLDR
Clinical and experimental data support the use of ∆PCO2 as a valuable help in the decision-making process in patients with hemodynamic instability as well as the physiological background allowing adequate interpretation of £ PCO2 at the bedside.
Central venous-to-arterial carbon dioxide difference as a prognostic tool in high-risk surgical patients
TLDR
A high PCO2 gap at admission in the postoperative ICU was significantly associated with increased postoperative complications in high-risk surgical patients and might be a useful tool complementary to central venous oxygen saturation as a therapeutic target.
Assessing Acid–Base Status in Circulatory Failure: Relationship Between Arterial and Peripheral Venous Blood Gas Measurements in Hypovolemic Shock
TLDR
In hypovolemic shock, the peripheral VBG does not demonstrate a higher CO2 concentration and lower pH compared to arterial blood, likely due to peripheral vasoconstriction and central shunting of blood to essential organs.
Do fluctuations of PaCO2 impact on the venous-arterial carbon dioxide gradient?
TLDR
Interestingly, central venous saturation also decreased signifi cantly when the RR was increased, and this could be an explanation for the increment of gut mucosal–arterial PCO 2 gradient observed with acute moderate hypocapnia.

Arterial-venous PCO2 gradient in early postoperative hours following myocardial revascularization.
TLDR
P(a-v)CO2 represents a useful even if aspecific parameter to monitor patients during the early postoperative period after myocardial revascularization, and was influenced by the metabolic rate, the body temperature, and the impaired CO2 elimination through the lungs.
Comparison of central-venous to mixed-venous oxygen saturation during changes in oxygen supply/demand.
TLDR
Although absolute values of ScvO2 are not sufficiently identical to SvO2 to calculate O2 uptake or pulmonary shunt precisely, close tracking of changes in the two sites across a wide range of hemodynamic conditions warrant further consideration of ScVO2 for patient monitoring of trends in O2 supply/demand.
Veno-arterial carbon dioxide gradient in human septic shock.
TLDR
dPCO2 patients with septic shock is related principally to cardiac output but apparently also to the degree of pulmonary impairment, and although dPCO 2 is larger in nonsurvivors, its prognostic value is modest.
Arterial‐venous carbon dioxide tension difference during severe hemorrhage and resuscitation
TLDR
These findings suggest that the adequacy of resuscitation after hemorrhage can be assessed using paired arterial and mixed venous pH and Pco2 values.

TLDR
It is concluded that the increase in the venous‐arterial Pco2 gradient in severe sepsis appears to be related to reductions in cardiac output.

TLDR
The ΔPCO2/C(a-v)O2 ratio seems a reliable marker of global anaerobic metabolism and would be helpful for a better interpretation of pulmonary artery catheter data.

Estimation of mixed venous PCO2 for determination of cardiac output in children.
TLDR
CO2-rebreathing techniques can be used to determine Q in children; the exponential method gives values that are similar to the equilibrium method with the downstream correction; and one prediction can be use for Q in adults and children.
