A sphygmomanometer ( / ˌsfɪɡmoʊməˈnɒmɪtər / SFIG-moh-mə-NO-mi-tər ), also known as a blood pressure monitor, or blood pressure gauge, is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, [1] and a mercury or aneroid manometer to measure the pressure. Manual sphygmomanometers are used ...
Systolic and diastolic arterial blood pressures are not static but undergo natural variations [7] from one heartbeat to another and throughout the day (in a circadian rhythm). They also change in response to stress, nutritional factors, drugs, disease, exercise, and momentarily from standing up. Sometimes the variations are large. Hypertension refers to arterial pressure being abnormally high ...
Auscultatory gap. 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 ...
Allen's test. Arteries of the hand. Purpose. examination of arterial blood flow to the hands. In medicine, Allen's test or the Allen test is a medical sign used in physical examination of arterial blood flow to the hands. It was named for Edgar Van Nuys Allen, who described the original version of the test in 1942. [1]
A major aim of treatment is to prevent, limit, or reverse target organ damage by lowering the person's high blood pressure to reduce the risk of cardiovascular disease and death. Treatment with antihypertensive medications may be required to control the high blood pressure.
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.
Ophthalmology. Ocular hypertension is the presence of elevated fluid pressure inside the eye ( intraocular pressure ), usually with no optic nerve damage or visual field loss. [1] [2] For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3] [4] Elevated intraocular pressure is an important risk factor ...
Intraocular pressure ( IOP) is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine this. IOP is an important aspect in the evaluation of patients at risk of glaucoma. [1] Most tonometers are calibrated to measure pressure in millimeters of mercury ( mmHg ).
