Effect of Multi Frequency Vibration Sputum Expulsion Combined with Inflation Sputum Expulsion Method on Preventing Ventilator-associated Pneumonia of ICU Patients
Objective To explore effect of multi frequency vibration sputum drainage combined with inflation sputum drainage on preventing ventilator-associated pneumonia(VAP)of ICU patients.Methods The paper chose 110 patients with artificial airways in our ICU from August 2021 to August 2022 as study subjects,and divided them into control group(n=55)and observation group(n=55)with random number table method.Control group was treated with multi frequency vibration sputum therapy,while observation group with multi frequency vibration sputum therapy combined with inflation sputum therapy.Sputum excretion,oxygenation capacity,and incidence of complications(VAP,atelectasis)was observed between two groups.Results After treatment,the 24-hour sputum output and suction frequency of two groups was lower than before treatment,that of observation group was less than control group(P<0.05).The levels of PaO2 and SpO2 of two groups were higher than before treatment,and levels in observation group were higher than control group(P<0.05).Incidence of VAP and atelectasis in observation group was significantly lower than control group(P<0.05).Conclusion Multi frequency vibration sputum expulsion combined with inflation sputum expulsion method can effectively improve sputum expulsion effect,oxygenation ability of of ICU patients,with good effect in preventing complications including VAP and atelectasis.
