Brief Summary:
This is a Quasi-experimental research design. The subjects are limited in intensive care unit within north medical center hospital. All subjects depend on ventilator and receive weaning plans. Experimental group is weaning with the support of negative pressure ventilator .The investigators collect basic personal variables in the questionnaire, APACHE Ⅱ scale, Dyspnea scale and arterial blood gas analysis and ventilator weaning index. Compare experimental group and control group data. Data will be Statistical analyzed by: descriptive statistics (such as: mean, standard deviation, median, frequency, percentage) and inferential statistics (such as: Independent T-test, Pair T-test, Mann-Whitney U test), P-value <0.05 will consider to be statistically significant.

Arm Intervention/treatment
No Intervention: Control group
Base on positive pressure ventilation with intubation and mechanical ventilator, weaning processes will undergo by Pulmonologists.
Experimental: Experimental group
Experimental group is weaning with the support of negative pressure ventilator.
Behavioral: negative pressure ventilator use
Body ventilators that assist ventilation by applying intermittent subatmospheric pressure around the thorax, abdomen, or airway and periodically expand the chest wall and inflate the lungs. They are relatively simple to operate and do not require tracheostomy. Chest cuirass is used in this study.

Primary Outcome Measures :
  1. Ventilator weaning rate [ Time Frame: 28 days ]

Secondary Outcome Measures :
  1. ICU stay [ Time Frame: 28 days ]
