Prehospital end-tidal carbon dioxide (ETCO2) can be predictive of outcome for a trauma patient.
Patient selection: trauma patient
Measurement: end-tidal CO2 in mm Hg or kPa
A high or rising ETCO2 is associated with survival.
Favorable ETCO2: >=30 mm Hg
A low or declining ETCO2 is associated with nonsurvival.
Unfavorable ETCO2: < 25 mm Hg
