- Intubation in ICU (hospitalized in ICU for >24 hours prior to intubation)
- Tachycardia (HR > 110)
- Renal dysfunction (BUN > 25)
- Acidemia (pH < 7.25)
- Creatinine (>2.0)
- decreased HCO3(<20)
*Threshold of 4 or more good Sp and Sn in predicting prolonged mechaniascal ventilation
Note: This study excluded neurological patients and therefore cannot be applied in the NSICU setting.
