HR, bpm 190 (120-235) 197.5 (125-235) 152.5 (125-205) 163.5 (130-225)
RR, b/m 85 (56-95) 92.5 (50-100) 82 (61-88) 90 (60-95)
SpO2, % 91 (79-100) 96 (91-100) 89 (68-95) 94.5 (80-99)
Values are presented as mean (range). HR: heart rate; RR: respiratory rate; SpO2: peripheral oxygen arterial saturation; bpm: beats per minute; b/m: breaths per minute; OLV-One-Lung Ventilation; TLV-Two-Lung Ventilation. There is no statistical difference between the OLV and TLV groups with respect to the 1st and last recordings, or percentage change for all three physical parameters.
