WebThe venous blood gas ( VBG) is a multi-component serum assessment of pH, blood gas tensions (P v O 2 and P v CO 2 ), bicarbonate (HCO 3 ), and the base excess. can be drawn from an IV catheter along with other bloodwork, unlike an arterial blood gas ( ABG ), does not accurately reflect (P a O 2)
WebSep 24, 2024 · The pH, obtained from arterial blood gas (ABG), should be the first value analyzed upon suspicion of an acid-base disorder. A low blood pH is referred to as an acidemia; acidemia results when an acid-generating process, known as an acidosis, creates an excess of H + ions.
