The effects of hypotension on differences between the results of simultaneous venous and arterial blood gas analysis.

Abstract

Hypotensive status is associated with an increase in the amount of difference between VBG and ABG analysis regarding pH, HCO(3), and BE, though the amount of increase does not seem to be clinically important. Studying the precise effects of replacing ABG with VBG on the clinical decision-making and the following outcomes is worth-while.
