Clinical efficacy of oscillatory positive expiratory pressure combined with oxygen atomization in the treatment of inpatients with airway mucus hypersecretion
Objective:To investigate the clinical efficacy of oscillatory positive expiratory pressure(OPEP)combined with oxygen jet atomization in the treatment of inpatients with airway mucus hypersecretion.Methods:Forty inpatients with airway mucus hypersecretion admitted to our hospital from January 2020 to January 2022 were randomly divided into control group and experimental group,with 20 cases in each group.The control group was treated with oxygen jet atomization,and the experimental group was treated with respiratory trainer combined with oxygen jet atomization.The clinical efficacy of the two groups after treatment was compared.Results:After treatment,the 24 h sputum volume in the experimental group was significantly lower than that before treatment(P<0.05),but there was no significant difference between the two groups(P>0.05).After treatment,the cough difficulty,sputum character,cough symptom,Borg score,clinical COPD questionnaire(CCQ)score and COPD assessment test(CAT)score of the two groups were significantly lower than those before treatment,and the cough difficulty,cough symptom,Borg,CCQ and CAT scores of the experimental group were better than those of the control group(all P<0.05).The hospitalization stay of the experimental group and the control group were(9.41±5.34)days and(9.17±3.88)days,respectively,with no significant difference between the two groups(P>0.05).Conclusions:OPEP combined with oxygen atomization can promote sputum excretion in hospitalized patients with airway mucus hypersecretion,and reduce the difficulty of cough,improve cough symptoms and dyspnea.
