Abstract

The term “respiratory entrainment” refers to of coupling patterns between the rhythm neuronal and mechanical of ventilator to achieve satisfactory synchrony. Respiratory effort stimulated by the mechanical inspiratory flow or reverse trigger (RT), has been recently demonstrated [1]. This asynchrony is difficult to showed without additional signals as esophageal pressure or electrodiaphragmatic signal.

Highlights

  • The term “respiratory entrainment” refers to of coupling patterns between the rhythm neuronal and mechanical of ventilator to achieve satisfactory synchrony

  • Over 4-month from December-2014 we studied a group of consecutive ventilated patients because they showed too high respiratory drive, beside they were sedated and assist-volume control mechanical ventilation was changed trying improve ventilator interaction

  • Entrainment pattern we evaluated by measure of mechanical and neural respiratory times (Ttotm, Ttotn), and repetitive phase of ventilatoy cycles

To use a method to differenciate this asynchrony by the standard signals of the ventilator, using an occlusion maneuver and to show the characteristics of this RT
