Baseline and ICU data for the 74 study patients. Predictors for intubation and hospital mortality on multivariate logistic regression analysis are also shown
| No | Mean (SD) | Median (range) | Predictor of intubation | Predictor of hospital mortality | |
|---|---|---|---|---|---|
| FEV1=forced expiratory volume in 1 second; FVC=forced vital capacity; Pao2, Paco2=arterial oxygen and carbon dioxide tension; Fio2=fractional inspired oxygen; NS=not significant. | |||||
