Accuracy of the HoMedics Walgreens Deluxe Arm Blood Pressure device (WGNBPA-540) compared with auscultation in 85 individuals.

ABSTRACT

PURPOSE: To determine whether the HoMedics Walgreens Deluxe Arm Blood Pressure device (WGNBPA-540) meets the Association for the Advancement of Medical Instrumentation and the Working Group on Blood Pressure Monitoring of the European Society of Hypertension International Protocol accuracy requirements. MATERIALS AND METHODS: Simultaneous auscultatory measurements by two observers were obtained in individuals during measurement with the HoMedics WGNBPA-540. Each individual had three measurements after a minimum of 10 min of rest and 1 min between readings. RESULTS: Two hundred and fifty-five triplicate measurements were made in 85 individuals. The observer minus the WGNBPA-540 mean systolic blood pressure/diastolic blood pressure differences were 0.92/-0.22 mmHg (± 0.4.51/4.42 mmHg standard deviation). The observer minus WGNBPA-540 device within 5 mmHg for the systolic blood pressure/diastolic blood pressure was 86.27/92.16%, within 10 mmHg was 99.61/97.65%, and within 15 mmHg was 100/98.82%. CONCLUSION: The HoMedics model, WGNBPA-540, meets the Advancement of Medical Instrumentation (methods 1 and 2) and the International Protocol accuracy standard requirement.
