VBG compared to ABG
pH .03 lower
PvCO2 5.8 higher
PvCO2 less than 45 on room air rules out hypercarbia (Journal of Emergency Medicine
Volume 28, Issue 4 , May 2005, Pages 377-379)
Venous is as good as arterial blood gases in DKA (Emerg Med Austr 2006;18:64)
pH was almost identical, bicarb was close enough
Central (SVC) pH, bicarb, BE, and lactate agrees with arterial (Emerg Med J 2006;23:622)
New method can calculate an ABG from a VBG (Emerg Med J 2009;26:268)
VBG is just fine for COPDers for pH, HCO3 and CO2 (Eur J Emerg Med 2010 Oct;7(5):246-8)
