Does the iHealth BP7 wireless wrist blood pressure monitor accurately measure blood pressure compared to reference measurements in adults?
The iHealth BP7 wireless wrist blood pressure monitor meets the ESH-IP revision 2010 validation criteria and is recommended for self-measurement in adults.
Objective The aim of this study was to validate the iHealth BP7 wireless wrist blood pressure monitor according to the European Society of Hypertension International Protocol (ESH-IP) revision 2010. Materials and methods A total of 99 pairs of test device and reference blood pressure measurements (three pairs for each of the 33 participants) were obtained for validation. The ESH-IP revision 2010 for the validation of blood pressure measuring devices in adults was followed precisely. Results The device produced 66, 87, and 97 measurements within 5, 10, and 15 mmHg for systolic blood pressure (SBP) and 72, 93, and 99 mmHg for diastolic blood pressure (DBP), respectively. The mean±SD device–observer difference was −0.7±6.9 mmHg for SBP and −1.0±5.1 mmHg for DBP. The number of participants with two or three device–observer differences within 5 mmHg was 25 for SBP and 26 for DBP; furthermore, there were three participants for SBP and one participant for DBP, with none of the device–observer differences within 5 mmHg. Conclusion On the basis of the validation results, the iHealth BP7 wireless wrist blood pressure monitor can be recommended for self-measurement in an adult population.
