Assessment:

While the technology used in the Oregon Tunstall BPU-329, to measure blood pressure, has been declared as being equivalent to that used in another device, not only has no evidence has been published to show that the devices were compared according to a protocol compliant with (EU) 2017/745 and MEDDEV 2.7/1 rev 4 but the results of the assessment on which the declaration has been based have not been published either and cannot be verified. However, there are validation studies proving clinical validation of the same measurement technology, according to other equivalence claims.

Accuracy AssessmentRecommendationBasis
MedavalNoneAlthough equivalence to another device is claimed, this has not been tested to MDR requirements.
BIHS (UK and IRL)Self-measurementImplied equivalence to the Oregon BPU330
ESH (Europe)Self-measurementThe BIHS recommendation, despite the absence of the scientific evidence required by the same authors' criteria.

Validation Publications for Equivalent Devices

Note: This is a provisional list, as equivalence according to EU Regulation 2017/745 (e.g. MEDDEV 2.7/1 rev 4) is not proven. Accordingly, these publications are not used in the assessment of star-ratings.
