Validation of the Rossmax AC1000f upper-arm blood pressure monitor in adults according to the British Hypertension Society Protocol.

Abstract

To evaluate the accuracy of the Rossmax AC1000f oscillometric upper-arm blood pressure monitor in adults according to the British Hypertension Society Protocol. Eighty-five subjects (male 42 and female 43) with a mean age of 48.1 years were recruited to fulfill the blood pressure distribution criteria of the British Hypertension Society Protocol in general population using the same arm sequential blood pressure measurement method. For each subject, we sequentially measured blood pressure using a mercury sphygmomanometer (two observers) and the AC1000f device (one supervisor). Data analysis was carried out according to the British Hypertension Society Protocol. A total of 255 comparison pairs were obtained for analysis. The device achieved grade A. The percentage of blood pressure differences within 5, 10 and 15 mmHg was 66.7, 92.2 and 98.0%, respectively, for SBP, and 64.7, 90.2 and 98.4%, respectively, for DBP. The average (±SD) of the device-observer differences was -0.5 ± 6.0 mmHg for SBP and -1.4 ± 5.9 mmHg for DBP, respectively. The automated upper-arm blood pressure monitor Rossmax AC1000f has passed the requirements of the British Hypertension Society Protocol, and hence can be recommended for blood pressure measurement in adults.
