Validation of two automatic devices, Omron HEM-6232T and HEM-6181, for self-measurement of blood pressure at the wrist according to the ANSI/AAMI/ISO 81060-2:2013 protocol and the European Society of Hypertension International Protocol revision 2010

The mean device–observer measurement difference was –0.9±5.7 mm Hg and 0.2±4.6 mm Hg for SBP and 0.5±4.9  mm Hg and 1.4±3.5  mm Hg for DBP, for HEM-6232T and HEM-6181, respectively, satisfying part 1 of the ESH-IP2. All differences for SBP and DBP in both devices satisfied part 2 of the ESH-IP2. The number of absolute differences in the values obtained using the devices and those measured by the observers fulfilled the requirements of the ANSI/AAMI/ISO and the ESH IP2.Conclusion: The Omron HEM-6232T and HEM-6181 devices met all the requirements of the ANSI/AAMI/ISO and the ESH IP2.
