Percept-based analysis of physiological indices. (A) Timing of 4-minute baseline and 1-minute post nausea rating transition windows are shown over a plot of a representative subject's nausea level. (B–G) Mean change in SCL, HR, respiratory rate, normalized HF, normalized LF, and LF/HF ratio reveal increases in SCL, HR, normalized LF, and LF/HF ratio with increasing nausea level. HF normalized decreased in response to increasing nausea level. Error bars indicate standard error of the mean. (+ 0.1>p>0.05,*0.05> p>0.01, **0.01>p>0.001, ***p<0.001).
