For many people, regular blood pressure measurements are part of everyday life. An upper arm cuff is used as standard. But there are also more handy devices – and hand is the keyword here: The Beurer BC 54 Bluetooth is a wrist cuff. It is also smart and transfers its measured values to the app on the smartphone. The test shows whether it performs as well as the test winner Omron M500 Intelli IT. You can read the entire test in the printed COMPUTER BILD edition 9/21 (first day of sale: April 23, 2021).
Beurer BC 54 Bluetooth: accuracy in the test
The most important property of a home blood pressure monitor is its accuracy. We checked them in the Schoen Clinic Neustadt in Holstein, where the chief physician of cardiology, Prof. Dr. Peter Radke, who tested the Beurer BC 54 several times on different people. A cuff from hospital operations, the Boso K2, served as a reference and the test device was allowed to allow up to 5 millimeters of mercury column (mmHg) difference with each measurement. For the test, medical personnel put the cuff on the wrist of the test subjects. Despite this, the cuff consistently delivered measurements that were too inaccurate. The upper blood pressure value (“systole”) was on average 13 mmHg off, the lower blood pressure value (“diastole”) it was on average 9 mmHg too imprecise. That is by far not enough! In practice, the deviation is likely to be even higher, as it is difficult for laypeople to put the device on in the correct position and firmly enough.
Setup and operation of the device
Starting a measurement is simple: by pressing the button, the cuff starts to inflate. A button is used to change users. The small display shows the measured values in large letters and is easy to read. The classification of the measured values on a traffic light scale is a bit lost because the manufacturer only uses a small arrow that is easily overlooked. The Beurer BC 54 reacts more sensitively than the competition to measurement errors – it even complains when the cuff is too loose or when you speak. But in the end, this accuracy is of no use in view of the overall inaccurate measured values.
Smart: see results in the app
If you want, you can connect the cuff to your smartphone. The transmission of the results to the app works after the initial setup with the app at the push of a button after the measurement. The “Beurer Health Manager” app prepares the data in a clear manner. However, there is no classification of the values. Good: The data only migrates to the manufacturer cloud if the user also wants it.
Beurer Health: terms and conditions and data protection
The editors had the general terms and conditions (GTC) and data protection conditions of the manufacturer app checked by an independent law firm. The experts came to the verdict satisfactory (grade 3) for the terms and conditions and sufficient for data protection (grade 4). The biggest shortcomings: The provider uses data for advertising purposes and transmits data to the USA without guaranteeing adequate security standards.
