Few studies have been conducted on blood pressure monitors and their use at high altitude. This study is the first to evaluate the accuracy of an automatic blood pressure monitor in a high-altitude environment following a standard validation protocol. The Omron HEM-7201 upper arm blood pressure monitor was tested for accuracy in Lhasa, Tibet, China (3650 m above sea level) according to the European Society of Hypertension International Protocol revision 2010 (ESH-IP2). Thirty-three participants received 9-10 sequential blood pressure measurements alternating between a mercury sphygmomanometer and the device. The mean device-observer measurement difference was 1.0+/-5.9 mm Hg for systolic blood pressure (SBP) and -3.1+/-4.6 mm Hg for diastolic blood pressure (DBP). Of the 99 measurement pairs analyzed, 72, 90 and 97 device readings were within 5, 10 and 15 mm Hg, respectively, of the observer measurements for SBP, and 68, 92 and 99 readings for DBP. The number of participants with at least two out of three measurements within 5 mm Hg was 27 for SBP and 25 for DBP. Three participants had no measurements within 5 mm Hg for either SBP or DBP. As a result, the Omron HEM-7201 passes the ESH-IP2 validation criteria and can therefore be recommended for use in adults in this setting.Journal of Human Hypertension advance online publiation, 7 March 2013; doi:10.1038/jhh.2013.4.
