Purpose

NAVA used the electrical activity of the diaphragm (EAdi) to initiate and deliver in proportion of an inspiratory assistance. During inspiration, EAdi signal occurred earlier than airflow or pressure variations in the airway. The investigators hypothesized that NAVA improved patient-ventilator synchrony and reduced inspiratory workload as compared with pressure support ventilation delivered at two different cycling criteria (25 and 50 %).

Estimated Enrollment:	15
Study Start Date:	December 2009
Estimated Study Completion Date:	November 2018
Primary Completion Date:	April 2011 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Active Comparator: PSV-ET 25 Pressure support ventilation with expiratory trigger set at 25 %.	Other: Expiratory trigger (ET) Varying the cycling criterion according to the percentage of peak inspiratory flow
Active Comparator: PSV-ET 50 Pressure support ventilation with expiratory cycling set at 50 %.	Other: Expiratory trigger (ET) Varying the cycling criterion according to the percentage of peak inspiratory flow
Experimental: NAVA NAVA level is adjusted to achieve similar peak inspiratory pressure levels than during PSV.	Device: NAVA Assisted mechanical ventilation according to the electrical activity of the diaphragm recorded with a 16-FR naso-gastric tube mounted with EMG electrodes Other Name: Neurally Adjusted Ventilatory Assist
