Effect of Nava on Weaning Outcome in Patients With Mechanical Ventilation

Nava level is set to maintain the target tidal volume: 6-10ml / kg (pbw). The trigger sensitivity is 0.5uv. The expiratory trigger sensitivity: the built-in software of the ventilator is set to 70% of the peak value of diaphragm electrical activity.

According to the doctor's experience, maintain the target tidal volume: 6-10ml / kg (pbw); trigger sensitivity: 1.5-2l/min, expiratory trigger sensitivity: 30% inspiratory peak flow rate.
