Outcome Measures
Primary Outcomes (2)
∆Raw (the Difference Between Measured and Target Airway Resistance)
The value can be expressed as relative deviation from target =(measured Raw - target Raw)/target Raw X100
Airway resistance will be recorded everyday. If a patient's ventilator was liberated less than 28 days, the day of liberation was the reported time frame. If the day of ventilator liberation was over 28 days, the 28th day was the reported time frame.
Rapidity of ∆Raw Change
The deviation of ∆Raw from the personal target, which was calculated as (measured Raw-target Raw)/target Raw multiplied by 100.
Airway resistance will be recorded everyday. If a patient's ventilator was liberated less than 28 days, the day of liberation was the reported time frame. If the day of ventilator liberation was over 28 days, the 28th day was the reported time frame.

Study Arms (2)
Individualized dosing
EXPERIMENTAL* Ventilator support * Determining personal target airway resistance * Bronchodilator:Salmeterol/fluticasone 4 puffs inhalation every 12 hours until ventilator discontinuation or the 28th day if ventilator-dependent * Bronchodilator:Ipatropium/salbutamol 1 vial inhalation every 6 hours for the first 3 days * Steroid:Methylprednisolone 40 mg intravenous injection every 8 hours for the first 3 days * Additional broncho-dilators inhalation: Salmeterol/fluticasone (Seretide) 4 puffs plus fenoterol (Berotec) 4 puffs inhalation if personal target airway resistance (measured every 8 hours) not met (until ventilator discontinuation or the 28th day if ventilator-dependent)
Fixed dosing
ACTIVE COMPARATOR* Ventilator support * Determining personal target airway resistance * Bronchodilator:Salmeterol/fluticasone 4 puffs inhalation every 12 hours until ventilator discontinuation or the 28th day if ventilator-dependent * Bronchodilator:Ipatropium/salbutamol 1 vial inhalation every 6 hours for the first 3 days * Steroid:Methylprednisolone 40 mg intravenous injection every 8 hours for the first 3 days * No additional bronchodilator given if personal target airway resistance (measured every 8 hours) not met
Interventions
Salmeterol/fluticasone (Seretide Evohaler) 4 puffs plus fenoterol (Berotec)(0.1mg/puff) 4 puffs inhalation when target airway resistance, measured every 8 hours, not met
