Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
These methods often involve an interface with health care professionals and frequently results are tarnished by a list of factors including variability in the individual's blood pressure, technical inaccuracies, anxiety of the patient, [6] inadequate cuff size of the instrument (sphygmomanometer) used to measure blood pressure, [7] recent ...
The mean, normal SA in healthy young adult females and males is 66° and 80°, respectively, [9] and very similar magnitudes are found in the elderly population (65 years and older). [10] In ECG analysis, the SA is categorized into normal (below 105°), borderline abnormal (105–135°) and abnormal (greater than 135°). [ 11 ]
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.
Patients who normally undergo ambulatory blood pressure monitoring are suggested to keep record on the periods of awake and asleep times, medication intake and periods when exposed to exercise. This allows the clinicians to eliminate the transition periods when blood pressure rapidly elevates.
Using the results of the blood pressure test, the health care provider will diagnose prehypertension or high blood pressure if: For an adult, systolic or diastolic readings are consistently higher than 120/80 mmHg. A child's blood pressure numbers are outside average numbers for children of the same age, gender, and height. [39]

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 ...
