Relation between change in heart rate, HSI_S1 and HSI_S2 with drop in SaO₂ during events with and without arousals (N = 58). No significant differences in the associated change in heart rate (A), HSI_S1 (B) and HSI_S2 (C) with drop in SaO₂ were observed. For the hypoxemia level of 6%, the changes in HR_HS (p < 0.05) and HSI_S1 (p < 0.01) were significantly different between events that terminated with arousals compared to those without arousals. Here, * indicates p<0.05 and ** indicates p<0.01. The color band shows the confidence interval of 0.95% and the bars indicate standard deviation.
