Web1 aug. 2024 · 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.
