Correlation between the change of Dyspnea-Visual Analog Scale (VAS) and the change in electromyographic (EMG) activity of the Alae nasi, parasternal intercostal muscles and diaphragm between the initiation and end of the spontaneous breathing trial. Change in dyspnea-VAS is expressed as the difference between dyspnea-VAS at the initiation and end of the spontaneous breathing trial. The EMG activity is described by area under the curve (EMGauc) and maximum (EMGmax). Values are normalized to EMG activity at initiation of the SBT and are expressed as the ratio of the EMG activity at the end of the SBT to the EMG activity at the initiation of the SBT
