Validation of three automatic devices for the self-measurement of blood pressure according to the European Society of Hypertension International Protocol revision 2010

OBJECTIVE: The aim of the present study was to validate the Omron HEM-7130, HEM-7320F, and HEM-7500F 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. We included 33 participants (20 men and 13 women for the HEM-7130 experiment; 18 men and 15 women for the HEM-7320F experiment; and 21 men and 12 women for the HEM-7500F experiment). The mean age of the participants was 49±15, 50±11, and 50±11 years in the respective studies. RESULTS: The mean differences between the device and the mercury readings for systolic and diastolic BP were as follows: HEM-7130, -1.8±5.3 and -0.1±4.0 mmHg, respectively; HEM-7320F, -0.9±4.7 and -1.9±4.4 mmHg, respectively; and HEM-7500F, -1.0±4.6 and -1.1±4.0 mmHg, respectively. These findings indicated that the device was reading lower than the mercury. However, the number of absolute differences between the devices and observers fulfilled the requirement of the ESH-IP revision 2010. CONCLUSION: The Omron HEM-7130, HEM-7320F, and HEM-7500F passed all the requirements of the ESH-IP 2010 revision. Therefore, we recommend these devices for the home measurement of BP in adults.
