The effects of epinephrine/norepinephrine on end-tidal carbon dioxide concentration, coronary perfusion pressure and pulmonary arterial blood flow during cardiopulmonary resuscitation
End-tidal CO2 concentration correlates with pulmonary blood flow during cardiopulmonary resuscitation and has been claimed to be a useful tool to judge the effectiveness of chest compression. A high concentration of end-tidal CO2 has been related to a better outcome. However, most authors have noticed a decrease in end-tidal CO2 concentration after administration of epinephrine, concomitant with a
