Experimental: Computer-assisted weaning
Group assigned to the computer-assisted weaning program
Device: Computer-assisted weaning program
Closed-loop, knowledge-based, computer-assisted wean program initiated at the start of ventilator weaning.
Other Name: Drager Evita Smartcare System
Active Comparator: Standard of care weaning
Group assigned to receive current, evidence-based, standard of care for discontinuation of mechanical ventilation.
Behavioral: Standard of Care weaning
Evidence-based standard of care weaning process.
- Duration of Weaning [ Time Frame: Continuous (median weaning duration was 2 days) ]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.
- Duration of ICU Stay [ Time Frame: from start of weaning to discharge from ICU, on average 1-2 weeks ]Duration of ICU stay after weaning initiation
- Duration of Mechanical Ventilation [ Time Frame: from start of weaning to liberation from ventilator, on average 1-2 days ]Duration of mechanical ventilation from weaning initiation
- Duration of Hospitalization [ Time Frame: from start of weaning to discharge from hospital, on average 1-2 weeks ]
- Inpatient Mortality [ Time Frame: 28 days ]proportion of patients in each arm who died in the hospital
- Sedation Requirements [ Time Frame: during weaning, on average 1-2 days ]measure was not recorded
- Number of Spontaneous Breathing Trials Prior to Extubation [ Time Frame: from start of weaning to liberation from ventilator, on average 1-2 days ]
- Complications (Death During Wean, Ventilator-associated Pneumonia During Wean, Self Extubation, Re-intubation) [ Time Frame: Duration of weaning (median 2 days) ]This outcome is a composite outcome of the total number of participants with any one of the above-listed weaning-associated complications.
