Clinical Efficacy Assessment
Evidence-based evaluation of clinical performance
Measurement Accuracy
Accuracy of systolic and diastolic readings compared to the auscultatory method, as per ESH/AAMI protocols.
Device is FDA 510(k) cleared. It has not been submitted for independent validation under ESH, AAMI, or Stride BP protocols. Accuracy is based on FDA clearance data.
Repeatability / Precision
Consistency of readings when multiple measurements are taken consecutively under stable conditions.
Testing showed high precision, with consecutive readings consistently falling within a 3-4 mmHg range. The VIBRA 9S sensor appears effective at filtering noise.
Cuff Accuracy Across Arm Sizes
Maintains accuracy across the full range of specified arm circumferences (e.g., small, standard, large cuffs).
The standard 22-42cm cuff provides consistent readings for most adult users. N/A (not available) on performance with larger or smaller cuff sizes.
Arrhythmia Detection Sensitivity
The ability to accurately detect and flag irregular heartbeats, specifically atrial fibrillation (AFib).
