Purpose:The Purpose of this study was to identify the physiological, psychological factors to successful weaning of mechanical ventilation in ICU patients.
Method:Data was collected by interview with the use of questionnaires from 70 ICU patients, who were mechanically ventilated more than 3days at Y university medical center. Data was analyzed with descriptive statics, t-test, and χ2 test, and Pearson Coefficient Correlation using SPSS WIN 12.0 program.
Result: ICU patients with mechanical ventilator during weaning period reported high levels of anxiety, moderate levels of stress, and fatigue. The physiological, psychological factors influencing ventilator weaning success were RSBI(p=0.007), stress(p=0.009), anxiety(p=0.020), depression(p=0.040), fatigue(p=0.001), and dyspnea(p=0.010). The RSBI factor was shown to have positive correlations with ventilator care periods, PaCO2, and fatigue. Dyspnea was also positively correlated with stress, anxiety, depression, and fatigue.
Conclusion:This study suggests that RSBI, stress, anxiety, depression, fatigue, and dyspnea are significant factors to successful weaning from mechanical ventilation.
