Abstract：Objective:To explore the effect of preoxygenation before tracheal intubation on the resuscitation efficacy and prognosis of critically ill patients .Methods:80 critically ill patients were randomly divided into the control group ( with immediate intubation ) and the experimental group ( with mask-mechanical ventilation ,preoxygenation before tracheal intubation ) ,40 cases were in each group .The du-ration of tracheal intubation ,the success rate of one-time intubation,the incidence of arrhythmia in the process of intubation ,fatality rate within 28 days and the parameters of arterial blood gas analysis ,respiratory mechanics and hemodynamics after mechanical ventilation for one hour were compared between the two groups .Results:There were statistically significant differences in the comparison of the duration of tracheal intubation ,the one-time success rate of intubation ,the incidence of arrhythmia in the process of intubation and fatality rate within 28 days between the two groups ( P<0.01);compared those with the control group after mechanical ventilation for one hour ,PaO2 ,PaO2/FiO2,PaCO2 and A-aD O2,HR,CVP and MAP were significantly improved (P<0.05,P<0.01).Conclusion:Preoxygenation before tra-cheal intubation can effectively set up airway at early stage and improve the pulmonary ventilation function so as to maintain the hemody -namics stable and increase the survival rate of the patients with CPCR .
