Orthostatic hypertension is a medical condition consisting of a sudden and abrupt increase in blood pressure (BP) when a person stands up. [1] Orthostatic hypertension is diagnosed by a rise in systolic BP of 20 mmHg or more when standing.
Documented goals for blood pressure include a reduction in the mean arterial pressure by less than or equal to 25% within the first 8 hours of emergency. [7] If blood pressure is lowered aggressively, patients are at increased risk of complications including stroke, blindness, or kidney failure. [6]
In contrast there is no evidence that blood pressure needs to be lowered rapidly in hypertensive urgencies, where there is no evidence of target organ damage; over-aggressive reduction of blood pressure is not without risks. [3] Use of oral medications to lower the BP gradually over 24 to 48h is advocated in hypertensive urgencies. [4]
“Although high blood pressure typically causes no symptoms and people may feel perfectly well, long-term high blood pressure has been conclusively shown to damage internal organs, particularly ...
Hypertensive encephalopathy is caused by an increase in blood pressure. Several conditions may evoke blood pressure elevation: acute nephritis, eclampsia, crises in chronic essential hypertension, sudden withdrawal of antihypertensive treatment.
Blood pressure is measured in units called millimeters of mercury, or mm Hg. Normal blood pressure is typically below 120/80 mm Hg. High blood pressure, or hypertension, is defined as anything ...
Uncontrollable increase in blood pressure can cause damage to the arteries that are present around kidneys, and thus restrict the blood to deliver. Due to inconsistent fluctuations in blood pressure, this can cause additional problems to people with pre-existing heart or blood vessel conditions such as angina , cerebral aneurysm or aortic ...
The bladder should be emptied before a person's blood pressure is measured since this can increase blood pressure by up to 15/10 mmHg. [91] Multiple blood pressure readings (at least two) spaced 1–2 minutes apart should be obtained to ensure accuracy. [92]
