Table 6 The nonlinear CVs of EBSs

From: Changes in bowel sounds of inpatients undergoing general anesthesia

Nonlinear CVs Calculation methods Physiological significance
RR The percentage of recurrent points falling within the specified radius Reflect the similarity of signal fluctuation
Lmean The mean of the diagonal lengths in recurrence plot Related to the separation velocity of adjacent trajectories
ENTR The Shannon information entropy of all diagonal line lengths A measure of signal complexity
TT The average length of vertical line structures Degree of system stability
