SpO2 (%) 98 (97–99) 97 (96–99) 0.9685
  1. HR: heart rate; bpm: beats per minute; RR: respiratory rate; mpm: movements per minute; SAP: systolic arterial pressure; MAP: mean arterial pressure; DAP: diastolic arterial pressure; ETCO2: end-tidal carbon dioxide concentration; ETISO: end-tidal isoflurane concentration; SpO2: pulse oxymetry. Mean ± SD; paired Student t-test (P < 0.05). Median (interquartile interval); Wilcoxon test (P < 0.05)
