Learning Objective 1: Our study results might offer important information for nurses to effectively assist weaning ventilator in COPD patients, decrease patients suffering,

Learning Objective 2: Our study results might offer important information for nurses to shorten hospitalization days.

Background: The purpose of the study was to investigate the related factors for weaning ventilator in patients with chronic obstruction pulmonary disease (COPD). Methods: Subjects were random selected from a medical center in northern Taiwan. Nursing assessment was used as a tool to evaluate patients with ventilator, which had a reliability .877 of Kappa (percentage of agreement). The collected data were analyzed in SPSS software. As the results, the factors including demographic data, physiological status, and mechanical ventilator setting were highly associated with weaning ventilator. Results: The important predicting variables for weaning ventilator on COPD patients were evaluated by odd ratios are as following: family- accompanied ( with/ without, Odds Ratio: 8.98), respiratory distress ( no/ with, Odds Ratio: 10.57), distension of the abdomen ( no/ with, Odds Ratio: 9.15),  muscle power( normal/ abnormal, Odds Ratio: 6.25), edema ( no/ with, Odds Ratio: 4.45), amount of intake and output ( normal/ abnormal, Odds Ratio: 3.23), end positive end expiratory pressure ( lower/ higher than 3cmH2O, Odds Ratio: 14.07), FiO2 (Odds RatioF4.81), tidal volume (Odds RatioF4.62), pressure support mode(Odds RatioF4.92) . Conclusions: Our study results might offer important information for nurses to effectively assist weaning ventilator in COPD patients, decrease patients’ suffering, and  shorten hospitalization days.
