Simultaneous validation of the Grandway MD2301 digital automatic blood pressure monitor by the British Hypertension Society and the Association for the Advancement of Medical Instrumentation/the International Organization for Standardization protocols

OBJECTIVE: The aim of this study was to determine the accuracy of the Grandway MD2301 digital automatic blood pressure monitor by the British Hypertension Society (BHS) and the Association for the Advancement of Medical Instrumentation (AAMI)/the International Organization for Standardization (ISO) protocols. PARTICIPANTS AND METHODS: A total of 85 participants were included for evaluation based on the requirements of the BHS and the AAMI/ISO protocols. The validation procedure and data analysis followed the protocols precisely. RESULTS: The device achieved A/A grading for the BHS protocol and maintained A/A grading throughout the low, medium and high blood pressure ranges. The device also fulfilled the requirement of the AAMI/ISO protocol with device-observer differences of -0.9±5.6 and 0.8±5.2 mmHg for systolic and diastolic blood pressure, respectively, for criterion 1, and -0.9±4.7 and 0.8±4.2 mmHg, respectively, for criterion 2. CONCLUSION: The Grandway MD2301 digital automatic blood pressure monitor achieved A/A grade of the BHS protocol and passed the requirements of the AAMI/ISO protocol in adults.
