简要总结
This study is aimed at patients who have been admitted to the respiratory care center of this hospital who meet the PMV conditions (defined as continuous use of the ventilator for at least ten days) who are about to receive the ventilator out of training. After obtaining the explanatory consent, they will undergo continuous complete Before and after spontaneous breathing training, collect various relevant physiological data of lung volume and ventilation perfusion distribution, and analyze and predict the correlation of ventilator detachment.

结局指标
主要结局
ventilation perfusion distribution measurement
时间窗: 16 weeks
1. Within 2 hours before starting the whole day of ATC, start measuring lung volume and ventilation perfusion distribution in SIMV+PS mode. 2. Start the 72-hour ATC mode, measure once within 2 hours; measure again after 24 hours. 3. Within 2 hours before and after the completion of the 72-hour ATC conversion to the 24-hour tracheostomy tube high flow oxygen, one measurement is made. 4. Measure once within 2 hours before and after the completion of 24-hour high-flow oxygen conversion to 5 consecutive days of spontaneous breathing training. 5. After the use of high flow oxygen starts, measure it every 24 hours until the 5th day.
