This is another article regarding comparison of VBG vs ABG. “Comparison of arterial and venous pH, bicarbonate, PCO2 and PO2 in initial emergency department assessment”. The other one was in critically ill patient but this one is among patient with diverse medical conditions. They studied 95 patients and their conclusions is venous blood gas analysis for pH, bicarbonate and PCO2 may be a reliable substitute for ABG analysis in the initial evaluation of an adult patient population presenting to the ED.
