The random-zero sphygmomanometer (RZS) was introduced later as a modified device to measure BP, for the purpose of reducing observer bias.

Methods: Omron HEM-907, a widely used automated oscillometric device in many epidemiologic surveys and cohort studies, was compared here with random-zero sphygmomanometers. In total, 201 participants aged 40-79 years (37 men) were enrolled and randomly assigned to one of two groups, with blood pressure measurement first taken by automated oscillometric devices or by random-zero sphygmomanometers. The study design enabled comparisons of blood pressure values between random-zero sphygmomanometers and two modes of this automated oscillometric device (automated and manual), and assessment of effects of measurement order on blood pressure values. Results: Among all participants, mean blood pressure levels were the lowest when measured with random-zero sphygmomanometers compared with both modes of automated oscillometric devices. Several variables, including age and gender, were found to contribute to the blood pressure differences between random-zero sphygmomanometers and automated oscillometric devices. Equations were developed using multiple linear regression after taking those variables into account to convert blood pressure values by random-zero sphygmomanometers to automated oscillometric devices. Conclusions: Equations developed in this study could be used to compare blood pressure values between epidemiologic and clinical studies or identify shift of blood pressure distribution over time using different devices for blood pressure measurements.

Wellcome Open Res 2019, 4:146 ( ) First published: 03 Oct 2019, 4:146 ( ) Latest published: 03 Oct 2019, 4:146 ( ) Introduction Due to the high prevalence of high blood pressure (BP) worldwide and its strong association with increased risk for cardiovascular disease (CVD), BP measurement is standard in clinical practice. In order to provide an accurate estimate of BP level and assess its influence on cardiovascular health, correct procedures and acceptable precision of the devices used for BP measurement are crucial in clinical and epidemiologic studies. The standard mercury sphygmomanometer (HgS), with a stethoscope to detect Korotkoff sounds 1, has been recognized as the gold standard for measuring BP for many years, though biases in this procedure, such as observer bias due to digit preference, may cause inaccurate measurements 2.
