title: Accuracy of the HoMedics Walgreens Deluxe Arm Blood Pressure device (WGNBPA-540) compared with auscultation in 85 individuals.
abstract: OBJECTIVE
  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.
  
  
  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%.
  
  
  CONCLUSIONS
  The HoMedics model, WGNBPA-540, meets the Advancement of Medical Instrumentation (methods 1 and 2) and the International Protocol accuracy standard requirement.
