Time series of physiological measures for one patient prior to unplanned intubation. Unplanned intubation occurs at zero, on the right edge of the plots. During this time period (A) mean heart rate dips, (B) heart rate standard deviation increases, (C) mean respiratory rate decreases, (D) respiratory rate standard deviation remains unchanged, (E) oxygen saturation remains unchanged, and (F) oxygen saturation standard deviation increases. Also during this time (G) correlation between heart rate and respiratory rate increases, (H) correlation between heart rate and oxygen saturation increases, (I) correlation between respiratory rate and oxygen saturation decreases, (J) cardiorespiratory coupling decreases, (K) apnea burden increases, and (L) the HeRO score increases.
