Venous blood gas (VBG) is frequently used in the neonatal unit as alternative for capillary blood gas (CBG). However, studies reporting correlation are conflicting and data on interchangeability in neonates are lacking.

Both ABG and CBG provide valuable information about a patient's acid-base balance, oxygenation, and ventilation status. However, there are distinct differences between these two methods that healthcare professionals need to consider. In this article, we will explore the attributes of ABG and CBG VBG, highlighting their similarities and differences.

abg cbg和vbg有什么区别? abg使用动脉血液，而cbg使用毛细血管血液，而vbg使用钢丝。因此，这是abg cbg和vbg之间的关键区别。abg是临床上最重要的测试。但是由于获得样品的各种困难，cbg和vbg是进行了两个替代测试。

Conclusions: There is a significant correlation in pH, PCO 2, PO 2, BE, and HCO 3 among ABG, VBG, and CBG values, except for a poor correlation in PO 2 in the presence of hypotension. Capillary and venous blood gas measurements may be useful alternatives to arterial samples for patients who do not require regular continuous blood pressure ...

Correlation of VBG and CBG with ABG are as follows: Venous Blood Gas (VBG) pH correlates well with ABG; PvCO2 is usually within 4-6 mmHg of PaCO2 on ABG (but a bigger gradient is seen in a patient with poor perfusion) Capillary Blood Gas (CBG) pH is comparable to the ABG reading; PaCO2 is comparable to the ABG reading .

2023年7月5日 · This guide describes the venous blood gas (VBG) test, explains key differences from an arterial blood gas (ABG), and provides an approach to VBG result interpretation. Understanding how a VGB differs from an ABG is important.

2018年4月12日 · Objective: We investigated the correlation and interchangeability of the components between VBG and CBG in infants admitted to the neonatal intensive care unit. Methods: In a prospective study in the neonatal unit in Leiden University Medical Center (Netherlands), simultaneously VBG and CBG were withdrawn …

2020年3月3日 · There is a significant correlation in pH, PCO2, PO2, BE, and HCO3 among ABG, VBG, and CBG values, except for a poor correlation in PO2 in the presence of hypotension. Capillary and venous blood gas measurements may be useful alternatives to arterial samples for patients who do not require regular co …

2021年8月1日 · Central venous blood gas (VBG) is a potentially more accessible alternative to ABG sampling. Current evidence suggests that pH and Pco2 obtained via peripheral VBG correlate well with ABG measurement. Nevertheless, the value of using central VBG to guide clinical decisions or as a surrogate for ABG is unclear.

In the intensive care unit, emergency department, and respiratory floors, many clinicians use venous blood gases (VBGs) instead of ABGs to estimate indices of ventilation and acid-base disturbance (ie, systemic carbon dioxide [CO 2] and pH).
