We also describe potential and pitfalls of the available bedside methods for drive assessment and explore classical and more “futuristic” interventions to control drive in ARDS patients.īreathing is generated by the rhythmic discharge of groups of neurons located in the brainstem which produces a neural signal directed to respiratory muscles to generate inspiratory effort and tidal breathing. We summarize the main determinants of neural respiratory drive and the mechanisms involved in its potentiation, in health and ARDS. In the present review, we focus on the physiological and clinical implications of control of respiratory drive in ARDS patients. However, excessive effort to breathe due to high respiratory drive may lead to patient self-inflicted lung injury (P-SILI), even in the absence of mechanical ventilation. Spontaneous breathing may offer multiple physiologic benefits in these patients, including decreased need for sedation, preserved diaphragm activity and improved cardiovascular function.

Neural respiratory drive, i.e., the activity of respiratory centres controlling breathing, is an overlooked physiologic variable which affects the pathophysiology and the clinical outcome of acute respiratory distress syndrome (ARDS).
