Expert reference in \(P_{\textrm{es}}\). a and b show two examples from two different patients, where the experts disagreed on whether patient activity occurred (a) and on the exact onset of activity (b). In both examples, the invalid annotations were not taken into account in further algorithm validation. For comparison, the sEMG curves and the results of the algorithms are also plotted in each case. However, the experts were blinded to these while evaluating \(P_{\textrm{es}}\). c provides an overview of the total number of annotated breaths in \(P_{\textrm{es}}\), including agreements and disagreements
