Venous blood gas (VBG) interpretation. Arterial blood gases (ABGs) are commonly used for estimating the acid-base status, oxygenation and carbon dioxide concentration of unwell patients. However, arterial blood can be difficult to obtain due to weak pulses or patient movement.
31 Αυγ 2021 · The veno-arterial difference in the partial pressure of carbon dioxide (Pv-aCO 2 gap) has been increasingly recognized as a reliable tool to evaluate tissue perfusion and as a marker of poor outcome during circulatory shock, and it should therefore be part of an integrated clinical evaluation.
10 Ιουλ 2023 · A venous blood gas (VBG) is an alternative method of estimating systemic carbon dioxide and pH that does not require arterial blood sampling.
26 Σεπ 2022 · The partial pressure of carbon dioxide (PCO2) is the measure of carbon dioxide within arterial or venous blood. It often serves as a marker of sufficient alveolar ventilation within the lungs. Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg or 4.7 to 6.0 kPa.
26 Αυγ 2021 · This study aimed at investigating whether changes in central venous-to-arterial CO2 difference (Δ-ΔPCO2) and central venous oxygen saturation (ΔScvO2) induced by volume expansion (VE) are ...
13 Μαΐ 2021 · ∆PCO 2 was calculated as the difference between the hindlimb venous carbon dioxide tension (PvCO 2) and hindlimb arterial PCO 2 (PaCO 2).
25 Ιουλ 2012 · The difference between mixed venous blood carbon dioxide tension (PvCO 2) and arterial carbon dioxide tension (PaCO 2), called ∆PCO 2 has been proposed to better characterize the hemodynamic status.
