Key result
Sphygmetrics SR-2 automatic BP recorder correlates highly with mercury sphygmomanometry for systolic and diastolic measurements.
Why the study?
The Sphygmetrics SR-2 Automatic Blood Pressure Recorder may reduce observer bias in epidemiologic blood pressure studies but requires comparison to the mercury sphygmomanometer.
Does the Sphygmetrics SR-2 Automatic Blood Pressure Recorder provide comparable blood pressure measurements to a mercury sphygmomanometer?

Does the Sphygmetrics SR-2 Automatic Blood Pressure Recorder provide comparable blood pressure measurements to a mercury sphygmomanometer?
Effect estimate: r = 0.93 and 0.92 for systolic, 0.84 and 0.85 for diastolic
The Sphygmetrics SR-2 Automatic Blood Pressure Recorder is comparable to auscultation for estimating systolic BP, reducing observer bias, but may be less reliable for diastolic BP in thin individuals.
Fortmann et al. (1981) conducted a cross-sectional in Blood pressure measurement (n=71). Sphygmetrics SR-2 Automatic Blood Pressure Recorder vs. Mercury sphygmomanometer (auscultation) was evaluated on Correlation of systolic and diastolic blood pressure measurements (r = 0.93 and 0.92 for systolic, 0.84 and 0.85 for diastolic). The Sphygmetrics SR-2 Automatic Blood Pressure Recorder showed high correlation with mercury sphygmomanometry for systolic (r=0.92-0.93) and diastolic (r=0.84-0.85) blood pressure measurements.
