Brief Summary: Daily lung ultrasound can help weaning from mechanical ventilation in difficult-to-wean adult patients. In this randomized trial, standardized lung ultrasound will be performed daily asssociated with standardized interventions aiming to decrease the total time in mechanical ventilation.
Detailed Description: This trial will be performed in two intensive care units (ICUs). After randomization, all patients in the intervention group will undergo daily lung ultrasounds before the next spontaneous breathing trial. The results from the lung ultrasound will indicate specific interventions to facilitate weaning:

* No sign of lung sliding (ultrasound finding suggestive of pleural movement): prompt evaluation for pneumothorax or mainstream intubation will be indicated;
* normal lung ultrasound (ultrasound A profile): the patient will be evaluated for deep vein thrombosis / pulmonary embolism and/or for reversible airway obstruction (e.g. uncontrolled asthma or COPD \[Chronic Obstructive Pulmonary Disease\] exacerbation)- followed by appropriate treatment. If the patient has COPD, non invasive mechanical ventilation must be used as mode of discontinuing mechanical ventilation;
* lung ultrasound shows pulmonary edema (ultrasound B profile): cardiogenic pulmonary edema will be differentiated from acute Respiratory Distress Syndrome (ARDS) - followed by appropriate treatment (e.g. a negative fluid balance of, at least, 1000 ml before the next spontaneous breathing trial);
* lung ultrasound shows asymmetrical patterns (ultrasound AB profile or Pulmonary Consolidation): the possibility of an uncontrolled infection will be investigated;
* presence of simple pleural effusion: diuretics will be indicated (for a negative fluid balance of, at least, 1000 ml before the next spontaneous breathing trial) or thoracocentesis at description of the assistant team;
* presence of complex pleural effusion: other image exam will be performed, and will be evaluated by the surgical team.
