WebBreathing air polluted with high CO content – carbon-monoxide poisoning This is clinically the most significant cause of increased COHb for two reasons. First it is a more common cause of increased COHb than endogenous production of CO, and secondly it can result in a much more severe increase in COHb. WebFor bicarbonate, the weighted mean difference between arterial and venous values was -1.41 mmol/L (n= 905), with 95% limits of agreement of the order of ±5 mmol/L. Regarding base excess, the mean arterio-venous difference is 0.089 mmol/L (n= 103).
