Obtained parameters of experiment 1 and 2 (not included in figures).

Values are displayed as mean ± standard deviation, RMSSDResp = root mean square of successive differences, Resp = respiratory rate, HRV = heart rate variability, TV = tidal volume, HF high frequency, LF = low frequency, Minute Vent = minute ventilation; Tidal Vol = tidal volume, SpO2 = blood oxygen saturation level, ratio I/E = inspiratory to expiratory time ratio, MF = mid frequency, Hc = compression entropy, CCE = cross conditional entropy, n.s. = not significant, n.d. = not done (ANOVA not significant).
