Heart rate on arrival (1/min) 388 89.9 ± 23.0 95 90.1 ± 22.5 293 89.9 ± 23.2 0.952
RR systolic on arrival (mmHg) 387 118.9 ± 32.1 95 116.5 ± 32.2 292 119.7 ± 32.0 0.391
RR ≤ 90 mmHg on arrival (%) 62 (16.0%)   20 (21.1%)   42 (14.4%)   0.124
SpO2 on arrival (%) 380 96.7 ± 9.0 93 97.0 ± 5.5 287 96.6 ± 9.9 0.557

  1. The proportion of patients with RR ≤ 90 mmHg on arrival is calculated from the patients with available blood pressure values. RR: Blood pressure.
