State Key Laboratory of Respiratory Disease Clinical Trial
Official title:
Study of Neural Inspiratory Time and Expiratory Delay in Patients and Healthy Subjects During Unassisted Spontaneous Breathing and Mechanical Ventilation.
To make these definitions of neural inspiratory time (Ti) and expiratory delay clearly.The present study was undertaken to examined the physiological signals of patients and healthy subjects during spontaneous breathing and noninvasive mechanical ventilation.
