Development of adaptive pneumatic tourniquet systems based on minimal inflation pressure for upper limb surgeries

Table 2 Results of single factor analysis for arterial occlusion pressure of upper extremities

	$\bar{X} \pm SD$	Pearson correlation coefficients r	P
Systolic blood pressure (mmHg)	115 ± 13	0.657	0.00
Diastolic blood pressure (mmHg)	67 ± 8	0.424	0.00
Upper extremity circumference (cm)	23 ± 3	0.716	0.00
Body mass index (kg/m ² )	21 ± 4	0.159	0.19
Arterial diameter (mm)	3 ± 0.5	0.436	0.00
Blood flow velocity (cm/s)	84 ± 18	0.280	0.02

Coefficients between AOP and systolic blood pressure, diastolic blood pressure, upper extremity circumference, BMI, arterial diameter and blood flow velocity were analyzed with Pearson correlation. The mean difference is significant at the 0.05 level.
