Duration of Weaning [ Time Frame: Continuous (median weaning duration was 2 days) ] [ Designated as safety issue: No ]
Duration of weaning was assessed as the time from the initiation of weaning (randomization) to the time of successful extubation (defined as 48 hours free of mechanical ventilation). Patients were followed for the duration of hospitalization and the time of weaning onset and successful liberation from the ventilator was noted.

Clinical Trial of a Computer-driven Weaning System for Patients Requiring Mechanical Ventilation
A Randomized Controlled Trial of Computer-Driven Weaning Compared With Standard of Care Weaning in Medical Patients Requiring Mechanical Ventilation

The purpose of this study is to compare the efficacy of a computer-assisted ventilator weaning system (Drager Smartcare) to our current standard of care in the medical intensive care unit.
