Overview

BPM-100 accuracy supports clinical consideration; extends device validation literature while leaving outcome data open.

Key Points

  • The study aims to test the accuracy of a new algorithm for the BPM-100 blood pressure monitor using previously collected data.
  • Stored pulse wave and cuff pressure data from 391 measurements were analyzed.
  • A new algorithm was developed from a subset of 136 measurements to enhance accuracy for higher systolic pressures.
  • The larger subset of 255 measurements was utilized to validate the algorithm's accuracy against a mercury sphygmomanometer.
  • Mean difference for systolic BP was -0.16 +/- 5.13 mmHg, with 73.7% within 5 mmHg, 94.9% within 10 mmHg, and 98.8% within 15 mmHg.
  • Mean difference for diastolic BP was -1.41 +/- 4.67 mmHg, with 78.4% within 5 mmHg, 92.5% within 10 mmHg, and 99.2% within 15 mmHg.
  • The algorithm passed the AAMI standard and received 'A' grade in the BHS protocol.

Structured PICO

Does the new algorithm for the BPM-100 automated oscillometric blood pressure monitor accurately measure blood pressure compared to a mercury sphygmomanometer reference?

P
Population
85 subjects (providing 255 measurements) from an independently conducted validation trial comparing the BPM-100(Beta) with a mercury sphygmomanometer
I
Intervention
New algorithm for the BPM-100 automated oscillometric blood pressure monitor
C
Comparator
Reference measurements (mean of two observers using a mercury sphygmomanometer)
O
Outcome
Mean difference +/- SD between the new algorithm BPM-100 and the reference, and percentage of measurements within 5, 10, and 15 mmHgsurrogate

The new algorithm for the BPM-100 automated oscillometric blood pressure monitor meets the AAMI standard and BHS protocol for accuracy.
