A&D MedicalUA-611BeurerBM 27
Overview
Released––
Measuring
TypeUpper armUpper arm
Irregular heartbeat detectionYesYes
AFib detection or ECG–No
MethodAutomatic oscillometric measurement with fuzzy-logic-controlled inflation; designed for adult home use; first on-sale date not establishedAutomatic oscillometric upper-arm measurement during deflation; BM 27 item 65818, distinct from BM 27+ and regional Limited Edition models. First on-sale date unconfirmed
AccuracyMaker specification ±3 mmHg pressure and ±5% pulse; pressure range 0–299 mmHg, systolic 60–279 mmHg, diastolic 40–200 mmHg and pulse 40–180 beats/minMaker specifies systolic and diastolic display accuracy ±3 mmHg and pulse ±5%; systolic range 50–280 mmHg, diastolic 30–200 mmHg and pulse 40–199 beats/minute
Clinical validationA&D UK claims ESH 2010 validation; Medaval identifies the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished. The US Validate BP listing covers UA-611 under ANSI/AAMI/ISO 81060-2:2018 with different cuff options; this does not establish direct validation of the supplied UK cuff configurationMaker claims clinical validation and ESH recognition, while its datasheet names technical identity to BPM63S. Medaval reports equivalence without published evidence or verifiable MDR compliance, rather than a directly published exact-device validation study; independent validation flag omitted
FeaturesIrregular heartbeat indicator, pressure progress bar, WHO classification indicator, stored-reading average and automatic power-off; irregular heartbeat indication is not a specific AFib diagnosisCuff-fit check, irregular-heartbeat warning, classification scale and automatic switch-off; no HSD resting indicator, AFib screening or ECG
