Validation of the SAW-102 wrist home blood pressure monitor according to the protocols of the British Hypertension Society, the Association for the Advancement of Medical Instrumentation, and the European Society of Hypertension

Abstract

This study demonstrated that SAW-102 meets the BHS, ESH, and AAMI standards when measurements are done at the heart level and when the manufacturer's specifications, regarding wrist circumference, are respected. Our data also indicate that exceeding 19.5 cm wrist circumference is accompanied by dramatic decrease of the accuracy of the device.

Validation of the Microlife BP A200 Comfort and W2 Slim automated blood pressure monitors in a general adult population according to the European Society of Hypertension and the ANSI/AAMI/ISO 81060-2

“…Similar to the results of an earlier study by Zaetta et al [8], elderly participants might have difficulty following recommendations to maintain a steady arm position necessary for the measurements. In practice, BP measurements are influenced by many factors, especially for wrist devices; the BP measurements may be even more influenced by the position of the wrist relative to the heart and flexion or hyperextension of the wrist [9].…”
