[Preliminary clinical comparative study of a new blood pressure instrument with wrist cuff]

The present article reports on the first test results of a new oscillometric blood pressure device with a wrist cuff in clinical application. The test was performed in two different methodical studies. Both studies included 154 patients, from which 542 comparative measurements were acquired. The evaluated mean differences of systolic and diastolic blood pressures are -for study 1-1.2 mmHg (standard deviation +/- 7.9 mmHg) and 0.9 mmHg (+/- 6.2 mmHg), for study 2 1.6 mmHg (+/- 7.4 mmHg) and 3.5 mmHg (+/- 6.7 mmHg) and show a good agreement with the method of Riva-Rocci/Korotkoff. The results are discussed in detail and conclusions for applicable fields of use for the device and for additional clinical studies are drawn.
