35094-2. 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.
The five Korotkoff sounds. There are five Korotkoff sounds: [7] Phase I: The first appearance of faint, repetitive, clear tapping sounds which gradually increase in intensity for at least two consecutive beats is the systolic blood pressure. Phase II: A brief period may follow during which the sounds soften and acquire a swishing quality.
An auscultatory gap, also known as the silent gap, [1] is a period of diminished or absent Korotkoff sounds during the manual measurement of blood pressure. It is associated with peripheral blood flow caused by changes in the pulse wave. [2] The improper interpretation of this gap may lead to blood pressure monitoring errors, [1][2] such as an ...
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 ...
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 the diastolic reading. [12] Usually, the blood pressure is read from the left ...
The mineral also assists in easing tension in blood vessel walls, which lowers blood pressure. The AHA recommends consuming 3,500 to 5,000 mg of potassium daily to prevent or treathigh blood ...
The blood pressure reading is recorded as two numbers, systolic and diastolic. The systolic blood pressure represents the amount of pressure the blood is applying against artery walls during heartbeats whereas the diastolic blood pressure shows while the heart is resting between beats.

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 ...
