Validation of the professional device for blood pressure measurement Microlife WatchBP Office in adults and children according to the American National Standards Institute/Association for the Advancement of Medical Instrumentation/International Organization for Standardization standard

ObjectiveTo assess the accuracy of the professional oscillometric blood pressure (BP) monitor Microlife WatchBP Office in adults and children according to the American National Standards Institute/Association for the Advancement of Medical Instrumentation/International Organization for Standardization (ANSI/AAMI/ISO) 81060-2:2013 standard.MethodsAdults and children (aged 3-12 years) were recruited to fulfil the age, sex, BP and cuff distribution criteria of the ANSI/AAMI/ISO standard using the same-arm sequential BP measurement method. Three cuffs of the test device were used for arm circumferences of 14-22, 22-32 and 32-42cm.ResultsA total of 115 participants were recruited and 88 were included in the analysis (51 adults and 37 children). For criterion 1, the meanSD of the differences between the test device and reference BP was -1.0 +/- 7.0/-4.7 +/- 5.4mmHg (systolic/diastolic). For criterion 2, the SD of the averaged BP differences between the test device and reference per participant was 5.15/4.77mmHg (systolic/diastolic).ConclusionThe professional Microlife WatchBP Office BP monitor fulfilled the requirements of the ANSI/AAMI/ISO validation standard for adults and children and can be recommended for clinical use.
