Key result
Calf blood pressure measurement showed poor agreement with arm measurement for systolic and diastolic pressures, but closer agreement for mean blood pressure (mean difference 2 mmHg).
Why the study?
Does calf blood pressure measurement accurately reflect arm blood pressure in preoperative patients?
Cross-Sectional (n=250)
Predetermined random order for measurement site
Does calf blood pressure measurement accurately reflect arm blood pressure in preoperative patients?
Mean Difference: 2 (95% CI 18.69–22.47)
Absolute Event Rate: 98.24% vs 96.34%
Calf blood pressure measurement shows poor agreement with arm measurement for systolic and diastolic pressures, but mean blood pressure shows closer agreement and may be used as an alternative when the arm is unavailable.

Calf BP warrants caution for systolic/diastolic values preoperatively; leaves open mean BP utility as surrogate pending validation.
Sareen et al. (2012) conducted a cross-sectional in Patients undergoing surgery under anaesthesia (n=250). Calf blood pressure measurement vs. Arm blood pressure measurement was evaluated on Mean blood pressure (MBP) (MD 2 mmHg, 95% CI 18.69-22.47). Calf blood pressure measurement showed poor agreement with arm measurement for systolic and diastolic pressures, but closer agreement for mean blood pressure (mean difference 2 mmHg).
