Correlations Between Ventilator Assessment Items and Ventilator Weaning
Correlations Between Ventilator Assessment Items and Ventilator Weaning Outcome n n 英文摘要 The purpose of this research was to study correlations between ventilator assessment items and ventilator weaning outcome. To understand the achieving rate before ventilator weaning, and found out the most effective predictors of ventilator weaning outcome after using the ventilator over 3 days. An explored and correlated design was used. A total of 70 cases that met the selection criteria were recruited in the study. Data were analyzed by percentage, mean, standard deviation, frequency, t-test, Chi-Square, Pearson correlation, and logistic regression. The major findings of this study were as follows: (1) In the successful weaning group, the totally achieving rate was 71%. The best achieving category among the six assessment categories was the psychological category. The lowest achieving category was the category of clinical laboratory data. The first five lowest achieving items were 「normal breathing sound」, 「Albumin ≧ 3. 5 gm/dl」, 「 spontaneous tidal volume>5 ml/kg」, 「rapid shallow breath index<105/bpm/L」, 「calcium level in 8. 5 -10 mg/dl」, 「magnesium level in 1. 7 - 2. 1 mg/dl」, and 「phosphorous level in 2. 5 -5. 5 mg/dl」. (2) Demographic characteristics, six assessment categories, the achieving rate of twenty-seven assessment items, and the time of ventilator using before weaning were not significantly correlated to the ventilator weaning outcome. (3) Age(r=-0. 38, p<. 01)and APRCHE II (r=-0. 34, p<. 01)were significantly correlated to ventilator weaning outcome. The achieving rate of twenty-seven assessment items (r=-0. 62, p<. 01), weaning profile (r=0. 42, p<. 01), arterial blood gas analysis(r=0. 28, p=. 02), psychological category(r=0. 63, p<. 01)were positive related to ventilator weaning outcome. The time of ventilator using before ventilator weaning(r=-0. 27, p=. 02)was negative correlated to ventilator weaning outcome. (4) The significant predictors of successful weaning included psychological category, age, clinical laboratory data, and blood gas data, the result of indicated of 61% variances. The results of this study would be valuable in improvement of care quality of ventilator weaning.
