Requires caution with wrist NIBP in practice; leaves open validation in patient cohorts.
Cross-Sectional (n=85)
Does wrist NIBP monitoring provide comparable blood pressure measurements to upper arm NIBP in volunteers?
Mean Difference: 10.6
Wrist NIBP overestimates blood pressure by approximately 10 mmHg compared to upper arm measurement, but can be a viable clinical alternative if compensated by subtracting 10 mmHg or elevating the wrist.
Daniela Brum Emerick (2002) conducted a cross-sectional in Normal blood pressure (n=85). Wrist NIBP monitoring vs. Upper arm NIBP measurement was evaluated on Mean arterial pressure difference (MD 10.6 mmHg). Wrist NIBP monitoring consistently overestimated mean arterial, systolic, and diastolic pressure by approximately 10 mmHg compared to upper arm measurement.
