MOESM1 of Information conveyed by electrical diaphragmatic activity during unstressed, stressed and assisted spontaneous breathing: a physiological study

Additional file 1: Table S1. Detailed lung function tests at baseline and in the presence of the 20 cmH2O/L/sec resistance. FVC: Forced Vital capacity, FEV1: Forced expiratory volume in one second. PEF: Peak expiratory flow. Res: Resistance. Figure S1. Effect of a resistance on peak Eadi (A) and PTPeso/min (B) during spontaneous non-assisted breathing. PTPeso/minute: esophageal pressure-time product by minute. Eadi: Electrical activity of the diaphragm. The middle line of box-and-whisker plot represents the median. The central box represents the values from the lower to upper quartile (25 to 75 percentile). The vertical line extends from the minimum to the maximum values. Figure S2. Over-assist during pressure support ventilation (PSV) indicated by absence of visible negative esophageal pressure drop. Note that peak electrical activity of the diaphragm (peak Eadi) is on average below 6 microvolts. Eso: esophageal.
