Abstract：Objective To summarize end -tidal carbon dioxide partial pressure ( PetCO2 ) monitoring application in pre -hospital respiratory support.Methods By monitoring the change of PetCO2 at the end of the numerical and the waveform of different forms, the problems existing in the respiratory support were analyzed in order to rectify.Results In 62 cases of PetCO2 monitoring patients, 34 cases was abnormal, 27 cases returned to normal after timely treatment, the percutaneous oxygen saturation( SpO2 ) at 95% ~99%in 12 cases, 90%~99%in 15 cases;7 patients did not return to normal, SpO2 maintained at 60%~80% in 3 cases, 40%~60% in 1 case, 3 cases below 40%. Conclusion PetCO2 monitoring can not only noninvasive monitoring of ventilation, also can reflect the circulation function and pulmonary blood flow, is commonly used, reliable clinical monitoring means, and gradually applied in emergency medicine and pre-hospital first aid.
