Abstract

BACKGROUND

Electronic sphygmomanometer is widely used in the households, medical institutions, and can be applied to the measurement of blood pressure and pulse at the same time. Currently, there are few studies on accuracy comparison among different sphygmomanometers, and strict standardized verification is needed to ensure the comparability of blood pressure data.

OBJECTIVE

The aim of the present study was to validate the Omron HEM-7120, Yuwell YE680A, and Cofoe KF-65B for monitoring upper arm blood pressure (BP) according to the European Society of Hypertension International Protocol revision 2010 (ESH-IP revision 2010).

METHODS

Three trained medical doctors validated the performance of these devices by comparing the data obtained from the devices with those of a standard mercury sphygmomanometer.

RESULTS

We included 33 participants for each experiment; and the mean age of the participants was 50.0±11.2(Omron HEM-7120 experiment), 49.5±13.7(Yuwell YE680A experiment), and 48.8±15.0 years (Cofoe KF-65B experiment) in the respective studies. The absolute differences between the devices and the mercury readings within 5, 10, and 15 mmHg were as follows: HEM-7120, 73/99, 94/99 and 96/99, respectively, for systolic BP and 73/99, 91/99, 96/99, respectively, for diastolic BP; Yuwell YE680A, 50/99, 79/99 and 91/99, respectively, for systolic BP and 67/99, 87/99, 95/99, respectively, for diastolic BP; and Cofoe KF-65B, 53/99, 79/99 and 91/99, respectively, for systolic BP and 65/99, 89/99, 96/99, respectively, for diastolic BP. The findings also indicated that the devices’ systolic blood pressure readings were higher than mercury (1.3 mmHg, 1.0 mmHg and 4.1 mmHg higher for the Omron, Yuwell and Cofoe devices, respectively), while diastolic readings were lower than mercury (2.0 mmHg, 1.1 mmHg and 3.3 mmHg lower, respectively).

CONCLUSIONS

The Omron HEM-7120 passed the requirements of the ESH-IP 2010 revision, while the Yuwell YE680A and Cofoe KF-65B failed.
