Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
Manual sphygmomanometer and stethoscope used to take blood pressure in clinic. Blood pressure is recorded as two readings: a higher systolic pressure, which occurs during the maximal contraction of the heart, and the lower diastolic or resting pressure. [11] In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being ...
An example of this phenomenon is measurement of blood pressure using the "pulse obliteration method" with a sphygmomanometer. At resting state the arterial critical closing pressure is ~ 20 mmHg . Critical closing pressure in arteries is higher than the mean vascular filling pressure that develops after death (~7 mmHg).

Mean blood pressure rises from early adulthood, plateauing in mid-life, while pulse pressure rises quite markedly after the age of 40. Consequently, in many older people, systolic blood pressure often exceeds the normal adult range, [33] if the diastolic pressure is in the normal range this is termed isolated systolic hypertension.
References range may vary with age, sex, race, pregnancy, [10] diet, use of prescribed or herbal drugs and stress. Reference ranges often depend on the analytical method used, for reasons such as inaccuracy, lack of standardisation, lack of certified reference material and differing antibody reactivity. [11]
