ObjectiveTo determine whether the oxygen cost of breathing (VO2 resp) may predict successful weaning from mechanical ventilation.DesignA prospective clinical study.SettingA polyvalent intensive care unit of a teaching hospital.PatientsThirty non-consecutive mechanically ventilated patients ready to wean. Successful weaning was considered when reintubation was not needed for 48 h after extubation.InterventionsSpontaneous breathing test with a t-tube. VO2 resp was measured with the Douglas bag method.ResultsSuccessful weaning was present in 20 (67%) of 30 patients. No patient with successful weaning needed tracheal reintubation. A cut-off value for VO2 resp
