For patients with difficult weaning, NAVA can shorten the time of mechanical ventilation, but there is no large-scale study to explore the effect of NAVA on the weaning success rate and mechanical ventilation time of patients with gas resection. Therefore, this study intends to compare the effects of NAVA and PSV on weaning success rate and mechanical ventilation time in patients with tracheotomy patients through a randomized controlled study.~It is a prospective, multicenter, parallel group, single blind, randomized controlled tria。
