Can NAVA Mode Reduce Mechanical Ventilation Day in Patients With COPD ?

Overview

Background： Neurally Adjusted Ventilatory Assist (NAVA) mode is a new mode of ventilator, using electronic potential of diaphragm to adjust tidal volume. At the same time, this mode can trigger and cycle-off inspiratory time by high sensitivity of electronic potential of diaphragm, increase patient-ventilator synchrony, reduce sedative drug, improve oxygenation, shorten mechanical ventilation day and reduce the rate of diaphragm atrophy. It can improve survival rate and hospital day of patients. Both the animal and human experiment have the effect of lung and diaphragm protection Effect： The results of this trial are expected to obtain electronic potential of diaphragm in patients with obstructive pulmonary disease. Reviewing the current literature, few related literatures have such data presentation. This trial hopes to evaluate whether the use of NAVA can reduce mechanical ventilation day by analyzing electronic potential of diaphragm in patients with obstructive pulmonary disease. Investigators expect that participants with obstructive pulmonary disease using NAVA mode will have significantly less mechanical ventilation day than using conventional mode

Outcomes

Primary Outcomes

ventilator-free days(VFDs)

Each day during the measurement period that participants are both alive and free of mechanical ventilation. A participants who is extubated on Day 2 of the study and remains alive and free of the ventilator for the remainder of the 28-day study period.

Time frame: up to 28 days
