EFFECTIVENESS OF DEEP BREATHING EXERCISE AND INCENTIVE SPIROMETRY ON OXYGEN SATURATION AND PEAK EXPIRATORY FLOW RATE IN POST EXTUBATION ICU PATIENTS: A QUASI-EXPERIMENTAL STUDY

Background: Reintubation of patients in the ICU due to respiratory failure is a serious problem in medical world. Supportive therapy is needed for breathing exercises to prevent reintubation due to respiratory muscle weak ness.Objective:Aims toanalyze effectiveness of deep breathing exercise and Incentive spirometry on oxygen saturation and peak expiratory flow rate in extubated patients.Methods: A quantitative, quasi-experimental design with 33 respondents (11 in the deep breathing group, 11 in the incentive spirom etry group, and 11 in the combined deep breathing and incentive spirom etry group), recruited through purposive sampling. The independent vari able was the combination of Deep Breathing and Incentive Spirometry, implemented according to the module guidelines. The dependent variables were oxygen saturation, measured by pulse oximetry, and peak expiratory flow rate, measured by a peak flow meter. Data were analyzed using a paired sample t-test.Results: Deep breathing exercises and incentive spirometry showed a significant effect on oxygen saturation, as shown in the com bined results (p = 0.000; Delta = 4.55). Peak expiratory flow rate also showed significant deep breathing exercise and incentive spirometry interventions, with the most significance value in the combination intervention (p = 0.000; Delta = 130.27).Conclusion: The combination of deep breathing exercises and incentive spirometry interventions showed greater effectiveness, sug gesting it may be a supportive intervention for post-extubation patients
