Fig. 3

Neuro-mechanical coupling (NMC) of diaphragm and parasternal intercostals (ICM) during two different weaning methods (left) and reduction of pressure support (PS) level (right). Values are depicted as median (interquartile range). The number of subjects in which EMG and Pes parameters could be determined differed per muscle and ventilation mode or PS level. For the diaphragm N = 20 (median) and ICM N = 18 (median). CSV continuous spontaneous ventilation, PC-IMV pressure-controlled intermittent mandatory ventilation, Pesamp/EMGamp esophageal pressure amplitude divided by EMG activity amplitude and PTP/EMGAUC/min pressure time product of esophageal pressure multiplied with the respiratory rate divided by integral of EMG signal over time during the inspiration multiplied with the respiratory rate
