This project will conduct a series of analysis of physiological and clinical data on tracheostomy patients who receive prolonged mechanical ventilation, hoping to find out the different manifestations of patients through the investigation by a variety of physiologic measurements, so as to understand whether different types of patients phenotype to derive different clinical strategies for liberation of the mechanical ventilator.

Patients who have undergone tracheostomy and still have a tracheotomy tube
Are at least 20 years old
Stable respiratory condition with inspired oxygen fraction not exceeding 50%
