- Method
- Automatic oscillometric upper-arm measurement; HEM-7154-E, distinct from M3 Comfort HEM-7155-E and M3 Comfort AFib HEM-7196-FLE. First on-sale date not established
- Accuracy
- Maker's pressure accuracy ±3 mmHg and pulse accuracy ±5% of displayed reading; systolic range 60–260 mmHg, diastolic 40–215 mmHg and pulse 40–180 beats/minute
- Clinical validation
- Maker manual states an 85-subject clinical investigation under EN ISO 81060-2:2014 and compliance with 2014 and 2019+A1:2020; K5 is used for diastolic pressure. No additional population validation is inferred, and blood pressure validation does not establish diagnostic accuracy of rhythm indicators
- Features
- Irregular-heartbeat, body-movement, cuff-wrap and high-blood-pressure indicators. No AFib detection or ECG recording; the manual supports displaying the average of the latest two or three readings taken within ten minutes, despite the UK web table marking averaging as absent. This is distinct from automatic consecutive three-reading measurement; the UK page's generic Upper Arm BPM & ECG category label does not describe an ECG capability on this model
