Prehospital ETCO2 predicts in-hospital mortality and metabolic disturbances

A study to determine the ability of prehospital end-tidal carbon dioxide (ETCO2) to predict in-hospital mortality compared to conventional vital signs. Of all prehospital vital signs, ETCO2 was found to be the most predictive and consistent for mortality, which may be related to an association with metabolic acidosis.
