Clinical characteristics of 86 mechanically ventilated difficult-to-wean patients included in this study.
Table 2.
Weaning parameters measured before and after tracheostomy.
Table 3.
Comparison of weaning parameters measured before and after tracheostomy in patients with weaning success and weaning failure.
Table 4.
Comparison of the changes in weaning parameters in patients with different weaning outcome and patients with different tracheostomy tube size.
Fig 2.
Comparison of weaning parameters between weaning success and weaning failure group.
Before tracheostomy, the weaning parameters were no difference between the two groups. After tracheostomy, the MIP, MEP, Vt, Ve and RSBI showed significant improvement in the weaning success group.

Comparison of weaning parameters between weaning success and weaning failure group.
Before tracheostomy, the weaning parameters were no difference between the two groups. After tracheostomy, the MIP, MEP, Vt, Ve and RSBI showed significant improvement in the weaning success group.
