Blood pressure varies over longer time periods (months to years) and this variability predicts adverse outcomes. [18] Blood pressure also changes in response to temperature, noise, emotional stress, consumption of food or liquid, dietary factors, physical activity, changes in posture (such as standing-up), drugs, and disease. [19]
A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
“The study suggests that monitoring blood pressure variability could be a vital addition to routine health checks, helping to spot patients who remain at risk despite appearing to have well ...
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 ...
Mayer waves are cyclic changes or waves in arterial blood pressure brought about by oscillations in the baroreceptor reflex control system. [1] [2] The waves are seen both in the ECG and in continuous blood pressure curves and have a frequency about 0.1 Hz (10-second waves).
A high blood pressure is present when the resting blood pressure is persistently at, or above, 130 over 80, or 140 over 90 mmHg. [2] [11] It is important to realize, children have much different numbers that depend on their age, and size. [12]

Secondly, high blood pressure is a silent disease and thus it is vital for all diabetics to regularly check their blood pressure or have it checked at a doctor's office on a regular basis. The American Diabetes Association recommends that all diabetics get their blood pressure measured by a health care professional at least 2-5 times a year. [94]
