RESUMO
Objective To explore the best humidifying methods of artificial airway by comparison of different humidifying approaches.Methods 124 patients were divided into the control group (60 cases) and the treatment group (64 cases).Two methods,continuous airway humidifying by the trace injection pump and continuous airway humidifying by oxygen atomization were adopted.The humidifying effect,tolerance rate of patients,the airway complications and nursing cost were compared between the two groups.Results The method of continuous airway humidifying by oxygen atomization had better effect,was easy to be tolerated,less complications and less cost.Conclusions Continuous airway humidifying by oxygen atomization is a safe,effective,low-cost method,it is easy to be tolerated by patients and is worthy of being popularized.
