Abstract：Objective:To investigate the application of airflow impaction for removing residual material from airways in reducing the incidence of ventilator-associated pneumonia(VAP)among intubated patients in intensive care units.Method:A total of 200 patients admitted to the First Affiliated Hospital of Xiamen University from January 2024 to December 2024 were selected.Using a random number table,they were divided into two groups,with 100 cases in each group.The control group received routine care,the observation group underwent airflow impaction to clear retained secretions from the endotracheal tube.The amount of cleared secretions,incidence ventilator-associated pneumonia(VAP),respiratory-related indicators,and patient recovery were compared between the two groups.Result:The amount of retained cleared secretions was higher,incidence of VAP was lower in observation group than those in control group,with statistically significant differences(P<0.05).Before intervention,there were no statistically significant differences respiratory rate and blood oxygen saturation between the two groups(P>0.05).After intervention,the respiratory rate and blood oxygen saturation observation were significantly higher in observation group than those in control group,with statistically significant differences(P<0.05).The duration of endotracheal intubation and ICU hospitalization observation were significantly shorter in observation group than those in control group,with statistically significant differences(P<0.05).Conclusion:Airflow impaction for clearing retained secretions from endotracheal tubes in critically ill patients has been shown to effectively increase the volume of secretions removed,reduce the incidence of VAP,improve respiratory-related indicators,and promote patient recovery.
