At any given time, 30-70% of patients in the intensive care unit (ICU) are receiving mechanical ventilatory support; 70-80% of them are rapidly weaned off this support, often within a few days. Weaning is more problematic in the remaining 20-30% of patients, usually because of unfavourable respiratory mechanics, residual disease processes, cardiac dysfunction, respiratory muscle weakness, high secretion volumes, or altered mental status.
