I'm Interested

   - Acute lung injury prior to randomization

   - Receiving mechanical ventilation through a tracheostomy tube prior to current hospital
   admission (patient who is ventilator dependent)

   - Presence of bilateral pulmonary infiltrates on admission if he or she has a history of
   bilateral pulmonary infiltrates (as evidenced by previous x-rays) that can reasonably
   explain the current degree of pulmonary infiltrates present.

   - Presentation due to pure heart failure and no other known risk factors for ALI.
