Comparison of Proportional Assist Ventilation And Neurally Adjusted Ventilator Assist (PAVANAVA)

February 4, 2014 updated by: Matthieu SCHMIDT, Pierre and Marie Curie University

Breathing Pattern Variability, Respiratory Discomfort and Work of Breathing in Proportional Assist Ventilation And Neurally Adjusted Ventilator Assist

In spontaneously breathing mechanically ventilated patients, the adequacy between the patient's demand and the level of respiratory support delivered by the ventilator is a major clinical issue. Neurally adjusted ventilator assist (NAVA) and proportional assist ventilation (PAV) have been developed to adapt the level of assistance to the patient's demand. These two modes have been compared to pressure support ventilation (PSV) but have not been compared to each other.
