1 paź 2017 · The venous-to-arterial difference of carbon dioxide ( p CO 2 delta) is a parameter than can be used to indicate tissue perfusion, and its determination therefore may be useful in these patients.
2 lut 2016 · The mixed venous-to-arterial carbon dioxide (CO 2) tension difference [P (v-a) CO 2] is the difference between carbon dioxide tension (PCO 2) in mixed venous blood (sampled from a pulmonary artery catheter) and the PCO 2 in arterial blood.
Alteration of tissue perfusion is a main contributor to organ dysfunction in high-risk surgical patients. The difference between venous carbon dioxide and arterial carbon dioxide pressure (pCO 2 gap) has been described as a parameter reflecting tissue hypoperfusion in critically ill patients who are insufficiently resuscitated.
8 lis 2024 · The main aim of the study whether changes in central venous-to-arterial CO2 difference (ΔP(v–a)CO2) and central venous oxygen saturation (ΔScvO2) induced by volume expansion (VE) are reliable parameters to define fluid responsiveness (FR) in sedated and mechanically ventilated septic patients.
26 sie 2021 · This study aimed at investigating whether changes in central venous-to-arterial CO 2 difference (Δ-ΔPCO 2) and central venous oxygen saturation (ΔScvO 2) induced by volume expansion (VE) are...
31 sie 2021 · In this chapter, we present the physiological and pathophysiological determinants of the Pv-aCO 2 gap and review its implications in the clinical assessment of circulatory shock. Under aerobic conditions, CO 2 is produced at the mitochondrial level as a by-product of substrate oxidation (pyruvate and citric acid cycle intermediates) (Fig. 1).
10 wrz 2021 · Applying Fick’s formula for CO 2 shows that the difference between the mixed venous and arterial CO 2 content equals the ratio between CO 2 production (VCO 2) and cardiac output.
