RESUMO
Objective To observe and study the changes of hemodynamic and respiratory mechanical parameters of patients with respiratory failure.Methods 75 patients with respiratory failure in our hospital during the time of March 2016 to May 2017 were set as the observation group, while 75 healthy persons with the same age were set as the control group.Then the hemodynamic indexes and respiratory mechanical parameters of the two groups were detected, and the detection results of observation group with different severity degree of disease were compared, and the relationship between the hemodynamic indexes, respiratory mechanical parameters and respiratory failure were analyzed with Logistic analysis. Results The hemodynamic indexes and respiratory mechanical parameters of observation group were all worse than those of the control group (P＜0.05), the hemodynamic indexes and respiratory mechanical parameters of observation group with servere disease were all worse than those of patients with mild and moderate disease, the results of patients with moderate disease were worse than those of patients with mild disease (P＜0.05), and the Logistic analysis showed the hemodynamic indexes and respiratory mechanical parameters all had close relationship to the respiratory failure. Conclusions The change of hemodynamic and respiratory mechanical parameters of patients with respiratory failure are greater, and the detection results of patients with different severity degree of disease have significant differences, so those items of patients with respiratory failure should be monitored and improveed.
