Key result
Sphygmomat 2 reads systolic BP ~5 mmHg higher than the Hawksley sphygmomanometer.
Why the study?
The accuracy of the Sphygmomat 2 semiautomatic blood pressure monitor compared to the Hawksley random zero sphygmomanometer was evaluated.
Does the Sphygmomat 2 semiautomatic blood pressure monitor provide accurate readings compared to the Hawksley random zero sphygmomanometer in people with a wide range of blood pressures?

Does the Sphygmomat 2 semiautomatic blood pressure monitor provide accurate readings compared to the Hawksley random zero sphygmomanometer in people with a wide range of blood pressures?
Answers are grounded in this paper and cite their sources.
The Sphygmomat 2 semiautomatic blood pressure monitor shows acceptable accuracy compared to a standard sphygmomanometer, suggesting it is a valuable instrument for general clinical use.
The Sphygmomat 2 blood pressure monitor is a compact and portable electronic device based on detection of Korotkoff sounds using a piezo-electric microphone. We have compared its accuracy with the Hawksley random zero sphygmomanometer, which is commonly used in epidemiological and pharmacological studies. Comparison of manometers was conducted by two trained observers on 49 people with a wide range of blood pressures. The Sphygmomat 2 was found to have a median difference of 5.2 mmHg for systolic and 1 mmHg for diastolic pressure, in both cases reading higher than the Hawksley sphygmomanometer. The portability, versatility and accuracy suggest that the Sphygmomat 2 is a valuable instrument for general clinical use.

Prior et al. (1990) reported a cross-sectional. Sphygmomat 2 blood pressure monitor vs. Hawksley random zero sphygmomanometer was evaluated on Accuracy (difference in blood pressure readings) (Median difference 5.2 mmHg (systolic) and 1 mmHg (diastolic)). The Sphygmomat 2 blood pressure monitor read higher than the Hawksley sphygmomanometer, with a median difference of 5.2 mmHg for systolic and 1 mmHg for diastolic pressure.
