Clinical validation<\/b><\/p>\n\n\n\n<p class=\"p8\">A reliable monitor must be tested against a clinical reference standard.<\/p>\n\n\n\n<p class=\"p8\">In the UK, this usually means it appears on a list approved by bodies such as:<\/p>\n\n\n\n<ul class=\"wp-block-list ul1\">\n<li>the British &amp; Irish Hypertension Society (BIHS)<\/li>\n\n\n\n<li>or equivalent international validation protocols<\/li>\n<\/ul>\n\n\n\n<p class=\"p8\"><span class=\"s2\">\ud83d\udc49<\/span> You can check validated devices here:<br>https:\/\/bihs.org.uk\/blood_pressure_technology\/find_a_professional_bp_monitor\/<\/p>\n\n\n\n<p class=\"p8\">If a device is <b>not validated<\/b>, don\u2019t buy it, no matter how many reviews it has.<\/p>\n\n\n\n<p class=\"p9\"><b>2. Upper-arm cuff (not wrist)<\/b><\/p>\n\n\n\n<p class=\"p8\">Upper-arm monitors are generally more reliable for home use.<\/p>\n\n\n\n<p class=\"p8\">Wrist monitors:<\/p>\n\n\n\n<ul class=\"wp-block-list ul1\">\n<li>can be accurate<\/li>\n\n\n\n<li>but only if positioned at <b>exact heart level<\/b><\/li>\n\n\n\n<li>are much more technique-sensitive<\/li>\n<\/ul>\n\n\n\n<p class=\"p8\">For most people, upper-arm is safer.<\/p>\n\n\n\n<p class=\"p9\"><b>3.
