Validation of Microlife BP W100 wrist device assessed according to the European Society of Hypertension and the British Hypertension Society protocols

Abstract

The objective of this study was to determine the accuracy of the Microlife BP W100 device for blood pressure measurement. The device evaluations were performed in 85 participants, by using both the protocol of the European Society of Hypertension (ESH) and the protocol of the British Hypertension Society (BHS). Initially, the data from 33 participants were examined according to the ESH protocol. Furthermore, 52 participants were then enrolled to fulfill the BHS protocol requirements. In all participants, sequential same arm measurements were made by two trained observers. The device passed all three phases of the ESH protocol for systolic blood pressure (SBP) and diastolic blood pressure (DBP) and was graded A according to the criteria of the BHS protocol for both SBP and DBP. The A/A grade was achieved in low (<130/80 mmHg), medium (130-160/80-100 mmHg) and high (>160/100 mmHg) blood pressure categories. Mean blood pressure difference between BP W100 and observers in the 85 participants was 0.1+/-5.3 mmHg for SBP and 1.1+/-3.4 mmHg for DBP, and thus, the device also met the requirements of the Association for the Advancement of Medical Instrumentation. In conclusion, these data show that the Microlife BP W100 wrist monitor satisfied the recommended ESH accuracy levels and achieved A/A grade of the BHS protocol across a wide range of blood pressure.

Menopausal Status and Metabolic Syndrome in Women in Climacteric Period Treated at a Clinic in Southern Brazil

“…Abdominal obesity was obtained by the average between two WC measurements. The blood pressure levels were measured at the wrist with a validated automatic digital device (BP3AF1-3), according to the guidelines of Association for the Advancement of Medical Instrumentation (AAMI) and British Hypertension Society (BHS) [23]. The woman remained sitting, without speaking, and at rest for at least 5 minutes.…”

Proposição de categorização de valores de pressão arterial e validação de esfigmomanômetro automático em adolescentes

“…O aparelho automático de punho Microlife® BPW100 está registrado no Ministério da Saúde/ANVISA (nº 10222460055) autorização vigente para uso com data indeterminada. Porém, após pesquisa bibliográfica e consultas a páginas da internet referentes a este assunto, foi encontrada uma referência à validação deste modelo em sujeitos adultos 103 , pelos protocolos BHS 95 e ESH 93 e nenhuma em grupos especiais (idoso, crianças, adolescentes e gestantes). A pertinência na escolha deste aparelho foi que este é o único aparelho de punho validado e comercializado no Brasil.…”
