SBP and corresponding applied TIP in group A1 and A2. SBP and corresponding applied TIP in group A1 and A2. In group A1 new designed tourniquet system based on the AOP prediction model allowed not different SBP and significantly lower TIP in the procedure of surgery compared with group A2. SBP were 113 ± 5 mmHg in group A1 and 110 ± 5 mmHg in group A2; TIP were 152 ± 17 mmHg (range, 135-168 mmHg) in group A1 versus constantly 250 mmHg in group A2.
