In emergently ventilated trauma patients low end-tidal CO2 and low cardiac output are associated and correlate with hemodynamic instability hemorrhage abnormal pupils and death

摘要

BackgroundIn a smaller experience, the authors previously demonstrated that end-tidal carbon dioxide (PetCO2) and cardiac output (CO) had a positive association in emergently intubated trauma patients during Emergency Department resuscitation. The aim of this larger study was to reassess the relationship of PetCO2 with CO and identify patient risk-conditions influencing PetCO2 and CO values.
