Prolongation of mechanical ventilation poses serious personal and financial threats to healthcare consumers.

The investigators objectives are create and implement an multidisciplinary evidenced-based ventilator-weaning protocol to assess whether a systematic approach compared with the physician's judgment only decreases time spent on the ventilator, complications of mechanical ventilation and length of stay in critical care unit.

Enrollment: 235
Study Start Date: January 2011
Study Completion Date: January 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Protocol-directed
Discontinuation of ventilation was based in multidisciplinary protocol.
Other: Multidisciplinary weaning-ventilator protocol
We implemented a multidisciplinary protocol for weaning from mechanical ventilation.This consist of a daily screening for readiness, performing a spontaneous breathing test, evaluation of signs of intolerance and decision on extubation.
Other Name: Weaning-ventilator protocol
No Intervention: Usual care
Discontinuation of ventilation was left entirely to the discretion of the physicians.
