Fig. 3From: Continuous assessment of neuro-ventilatory drive during 12 h of pressure support ventilation in critically ill patientsIndividual neuro-ventilatory drive trend throughout the study. Each point represents the electric diaphragmatic activity peak (EAdiPEAK) of a single breath. The two red lines represent the 5–15 μV EAdiPEAK range depicting the “Normal” neuro-ventilatory driveBack to article page
