Comparison of vital signs between pre- and post-distractions in the 4 groups. a Comparison of P between pre- and post-distraction. b Comparison of SpO2 between pre- and post-distraction. c Comparison of SBP between pre- and post-distraction. d Comparison of DBP between pre- and post-distraction. The white bar indicates the value at pre-distraction. The gray bar indicates value at post-distraction. DBP, diastolic blood pressure; P, pulse; SBP, systolic blood pressure; SpO2, peripheral blood oxygen saturation; *p <  0.05; **p <  0.005; ***p <  0.001
