Abstract

Objective

The aim of the present study was to evaluate the accuracy of the automated oscillometric wrist blood pressure monitor AVITA BPM17 for home blood pressure monitoring according to the International Protocol of the European Society of Hypertension revision 2010.

Participants and methods

Systolic and diastolic blood pressures were sequentially measured in 33 adult Chinese (19 men, 45.7 years of mean age) using a mercury sphygmomanometer (two observers) and the AVITA BPM17 device (one supervisor). Ninety-nine pairs of comparisons were obtained from 33 participants for judgments in two parts with three grading phases.

Results

The AVITA BPM17 device achieved the targets in part 1 of the validation study. The number of absolute differences between device and observers within 5, 10, and 15 mmHg was 94/99, 98/99, and 98/99, respectively, for systolic blood pressure and 92/99, 99/99, and 99/99, respectively, for diastolic blood pressure. The device also fulfilled the criteria in part 2 of the validation study. Overall, 32 participants for both systolic and diastolic blood pressure, respectively, had at least two of the three device–observerss differences within 5 mmHg (required ≥24). None had all the three device–observers comparisons greater than 5 mmHg for systolic and diastolic blood pressure.

Conclusion

The AVITA wrist blood pressure monitor BPM17 has passed the requirements of the International Protocol revision 2010, and hence can be recommended for home use in adults.
