Objective The aim of this study was to validate the iHealth BP5 wireless upper arm blood pressure (BP) monitor according to the European Society of Hypertension International Protocol (ESH-IP) revision 2010.

Materials and methods The ESH-IP revision 2010 for validation of BP measuring devices in adults was followed precisely. A total of 99 pairs of test device and reference BP measurements (three pairs for each of the 33 participants) were obtained in the study.

Results The device produced 71, 89, and 97 measurements within 5, 10, and 15 mmHg for systolic blood pressure (SBP) and 73, 90, and 99 mmHg for diastolic blood pressure (DBP), respectively. The mean±SD device−observer difference was −1.21±5.87 mmHg for SBP and −1.04±5.28 mmHg for DBP. The number of participants with two or three device−observer differences within 5 mmHg was 25 for SBP and 28 for DBP. In addition, three participants had no device−observer difference within 5 mmHg for SBP and none of the participants had the same for DBP.

Conclusion According to the validation results on the basis of the ESH-IP revision 2010, the iHealth BP5 wireless upper arm BP monitor can be recommended for self/home measurement in an adult population.
