Primary Outcome Measures:

Total ventilation time during intensive care unit stay.

Secondary Outcome Measures:

Time in the zone of respiratory comfort during invasive mechanical ventilation
Number of ventilator alarms during invasive mechanical ventilation
Number of ventilator manipulations during invasive mechanical ventilation
Length of ICU and hospital stay
28-day and 90-day mortality

Estimated Enrollment:	300
Study Start Date:	March 2007
Study Completion Date:	August 2008
Primary Completion Date:	August 2008 (Final data collection date for primary outcome measure)

Detailed Description:

During the weaning process vigilance, pulmonary mechanics and respiratory drive of the patient are changing. Consequently, ventilation settings have to be modified very often. The modifications can be conducted either according to a weaning protocol or automatically by an expert system (SmartCare/PS). This trial compares protocol-guided weaning with automatic weaning in post-surgical patients and examines the effect on total ventilation time, numbers of manipulations and alarms of the ventilator, length of stay in the ICU and in the hospital, 28- and 90-day mortality.
