Summary

The onset and offset of the neural inspiratory time are fundamentally important measurements in studies of patientventilator interaction, where the level of assistance delivered by the ventilator is controlled by the patient's demand. The onset of neural inspiratory time can be determined in esophageal pressure, transdiaphragmatic pressure, and EMG signals. The investigator compare the onset measured by EMG, esophageal and transdiaphragmatic pressure, and consider that the correlation between them is well in different conditions.

Interventions

DEVICE

inspiratory threshold load device

Before experiment ,every subject use a flanged mouthpiece attached to a manually operated occlusion valve in order to measure maximal inspiratory pressure (MIP)at functional residual capacity . And then, the healthy subjects will be increased the neural respiratory drive by increasing the pressure in a water-sealed inspiratory threshold loading device. At last, all subjects will do Incremental cycle ergometry test with the assisstance of NPPV.
