And rightly so: some situations require immediate attention. But not every elevated pressure is an emergency. The key is to distinguish between \u201cvery high blood pressure\u201d and \u201chigh blood pressure with damage or alarm symptoms,\u201d and to know what to do at that moment without making things worse.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The most important<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It is considered <strong>emergency<\/strong> when the pressure is very high and there is also <strong>warning signs<\/strong> or suspected organ damage (brain, heart, kidney, eyes).<\/li>\n\n\n\n<li>If the pressure is high but <strong>you feel stable and without alarm symptoms<\/strong>, is usually a <strong>hypertensive urgency<\/strong>requires prompt medical assessment and adjustment, but does not always require an ambulance.<\/li>\n\n\n\n<li>Do not self-medicate with \u201cextra doses\u201d without indication.

Do this:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Sit for 5 minutes, back flat, feet on the floor.<\/li>\n\n\n\n<li>Do not talk during the measurement.<\/li>\n\n\n\n<li>Secure bracelet of the correct size and arm at heart level.<\/li>\n\n\n\n<li>Repeat 2 times (1 minute apart) and record the average.<\/li>\n<\/ol>\n\n\n\n<p>If you would like to review goals and technique, check out <a href=\"https:\/\/drakarlacastolo.com\/en\/blog\/diagnostic-evaluation\/blood-pressure-goals-home-blood-pressure-measurement\/\">blood pressure: goals and measurement at home<\/a> and the article by <a href=\"https:\/\/drakarlacastolo.com\/en\/blog\/diagnostic-evaluation\/hypertension\/\">hypertension<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When is it a real emergency (warning signs)?<\/h2>\n\n\n\n<p>Seek immediate attention (emergency room\/ambulance) if very high blood pressure is accompanied by any of these symptoms:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Chest pain or pressure, or significant shortness of breath (may be related to cardiac events).
