Table 3 Factors associated with successful weaning and survival in mechanical ventilation patients as determined by using stepwise logistic regression

From: Prolonged mechanical ventilation in a respiratory-care setting: a comparison of outcome between tracheostomized and translaryngeal intubated patients

  Successful weaning Survival
  OR (95% CI) P value OR (95% CI) P value
APACHE II <18 0.61 (0.48-0.79) < 0.01* 0.61 (0.47-0.79) < 0.01*
Albumin >2.5 g/dL 1.54 (1.22-1.95) < 0.01* 1.80 (1.40-2.31) < 0.01*
BUN <40 mg/dL 0.54 (0.42-0.70) < 0.01* 0.45 (0.34-0.59) < 0.01*
Performing tracheostomy 1.34 (0.99-1.82) 0.06 1.72 (1.26-2.34) < 0.01*
  1. Abbreviations: APACHE II, Acute Physiology and Chronic Health Evaluation II; BUN, blood urea nitrogen; OR, odds ratio. An APACHE II score >18 indicates more-severe disease. Albumin >2.5 indicates adequate nourishment. BUN >40 indicates abnormal metabolism. *A variable significantly associated with successful weaning or survival (P < 0.05).
