Brief Summary:
Neurally adjusted ventilatory assist (NAVA) is a new concept of mechanical ventilation. NAVA delivers assistance to spontaneous breathing based on the detection of the electrical activity of the diaphragm. The investigators will study the effects of non-invasive NAVA in respiratory muscle unloading in healthy volunteers.

Condition or disease Intervention/treatment Phase
Healthy Device: Neurally adjusted ventilatory assist Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 16 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Unloading of the Respiratory Muscles Using Non-invasive Neurally Adjusted Ventilatory Assist in Healthy, Resistively Loaded Volunteers
Study Start Date : July 2009
Actual Primary Completion Date : January 2010
Actual Study Completion Date : January 2010
