Full textVentilatory support must be tailored to the load capacity balance of the respiratory system to avoid patient-ventilator dysharmony as it may lead to patient-ventilator asynchronies and dyspnea. Minimizing this dysharmony is crucial. Neurally Ventilatory Assist Ventilation (NAVA) and Proportional Assist Ventilation (PAV) modes may improve patient-ventilator interaction. We showed in this work that PAV and NAVA both prevents overdistension, restores breath by breath variability of the breathing pattern and improves neuromechanical coupling and patient- ventilator asynchrony in fairly similar ways compared to pressure support ventilation. In addition the use of NAVA with non-invasive ventilation may also improve patient-ventilator interaction. We also demonstrated that dyspnea is a frequent issue in mechanically ventilated ICU patients and it can be difficult to assess when the patient is unable to report it. Surface electromyograms of extradiaphragmatic inspiratory muscles provides a simple, reliable and non-invasive indicator of respiratory muscle loading/unloading in mechanically ventilated patients. Because this EMG activity is strongly correlated to the intensity of dyspnea, it could be used as a surrogate of respiratory sensations in mechanically ventilated patients, and might, therefore, provide a monitoring tool in patients in whom detection and quantification of dyspnea is complex if not impossible. These data provide a better understanding of patient-ventilator dysharmony. Further studies are needed to evaluate the possible clinical benefits of NAVA and PAV on clinical outcomes and the impact of an early detection of dyspnea in mechanical ventilation

Full textThe brainstem respiratory centers are in charge of breathing regulation. Their output is transmitted to the inspiratory muscles. Respiratory drive monitoring can be performed using the electrical activity of the diaphragm (Eadi) or the measurement of the occlusion pressure at 100 ms (P0.1). Monitoring these parameters should allow improving the delivered ventilator assist. Few data regarding the normal values of Eadi and P0.1 and their variations in non-physiological situations are available. The question of the reliability of the bedside measurements also remains opened.This thesis project aimed at increasing our knowledge on Eadi and P0.1 measurements. The studies performed allowed 1. better characterizing Eadi and P0.1 normal values in physiological and non-physiological situations. 2. demonstrating that Eadi maximal value well reflects inspiratory drive intensity, 3. demonstrating that Eadi monitoring provides additional information compared to respiratory profile and inspiratory effort monitoring, 4. demonstrating that Eadi and P0.1 are well correlated, 5. demonstrating that Eadi can be used to improve the ventilator settings during pressure support and that this strategy allows improving patient-ventilator synchrony. 6. showing that the P0.1 variations are well reflected by the P0.1 measured by the ventilators, 7. demonstrating that overall the P0.1 measured by the ventilators underestimate the reference P0.1. Additional studies in more patients and studies designed to assess the impact on patient’s outcome of using Eadi and P0.1 monitoring should be perform before recommaending these monitorings as a standard procedure in ventilated patients
