Shown are the pre-tracheostomy conditions in the 163 patients who underwent tracheostomy, and differences between patients who weaned successfully and those who failed to wean. AST, aspartate aminotransferase; CNS, central nervous system; FiO2, fractional inspired oxygen; PaO2, arterial oxygen tension; PaCO2, arterial carbon dioxide tension; WBC, white blood cell.
