Abstract

OBJECTIVE: This study aimed at verifying the accuracy of three automated electronic oscillometric blood pressure measuring devices, namely Omron M5-I (home use upper arm monitor), R5-I (home use wrist monitor) and HEM-907 (professional use upper arm monitor) according to the European Society of Hypertension International Protocol in elderly individuals. METHODS: Sequential measurements of systolic and diastolic blood pressure were obtained in 33 participants (aged ≥ 75 years) using the mercury sphygmomanometer (two observers) and each of the tested devices (one supervisor). A standard adult cuff was always employed during the study because all participants had an arm circumference compatible with such a cuff. According to the European Society of Hypertension validation protocol 99 couples (three pairs per patient) of test device and reference blood pressure measurements were obtained during phase 1 (15 participants studied) and phase 2 (a further 18 participants) for each electronic monitor. RESULTS: All devices successfully passed the validation study with a mean (±SD) device-observer difference for systolic and diastolic blood pressure of 0.2±3.6/0.2±3.9 mmHg (Omron M5-I), -1.5±6.2/-0.7±3.7 mmHg (Omron R5-I), and 0.1±5.1/-1. 9±4.2 mmHg (Omron HEM-907). SD of the mean difference was lower and thus the precision was better for diastolic than for systolic blood pressure, and for the Omron M5-I than for the other two devices. CONCLUSIONS: According to the results of the validation study based on the European Society of Hypertension International Protocol the Omron M5-I, R5-I, and HEM-907 may be recommended for clinical use in elderly individuals, without atrial fibrillation or frequent ectopic beats.
