we hypothesized that a carbon dioxide ( co2 ) consuming buffer like tromethamine would reduce and sodium bicarbonate would increase the respiratory acidosis of mixed venous blood , which had recently been demonstrated in our laboratory , tromethamine did decrease and sodium bicarbonate did increase both arterial and mixed venous co2 during cardiopulmonary resuscitation ( cpr ) .
