Measurement of blood pressure is an important diagnostic and monitoring procedure.

Metrics details. The oscillometric method of measuring blood pressure with an automated cuff yields valid estimates of mean pressure but questionable estimates of systolic and diastolic pressures. Existing algorithms are sensitive to differences in pulse pressure and artery stiffness. Some are closely guarded trade secrets. Accurate extraction of systolic and diastolic pressures from the envelope of cuff pressure oscillations remains an open problem in biomedical engineering.

Hales first measured blood pressure in by inserting tubes directly into the arteries of animals. Non-invasive techniques for the measurement of blood pressure have been in existence since the early s, although Riva Rocci, an Italian physician, is credited with developing the first conventional sphygmomanometer in In , Nicolai Korotkoff described various sounds while auscultating over the brachial artery during deflation of a Riva Rocci cuff. Blood pressure measurement was first used during anaesthesia by Cushing in Now it is part of the minimum standard of patient monitoring as recommended by the Association of Anaesthetists of Great Britain and Ireland and should be measured in all patients undergoing, and recovering from, general anaesthesia, regional anaesthesia and sedation. Intermittent, non-invasive systems require three key components: A cuff is placed circumferentially around the limb. Most commonly the upper arm is used although it is possible to use the forearm or leg when the upper arm is inaccessible, for example due to surgical requirements.

Principles and techniques of blood pressure measurement.

Arterial blood pressure is most commonly measured via a sphygmomanometer , which historically used the height of a column of mercury to reflect the circulating pressure. For each heartbeat, blood pressure varies between systolic and diastolic pressures. Systolic pressure is peak pressure in the arteries, which occurs near the end of the cardiac cycle when the ventricles are contracting.

Она поймет. Честь. Страна. Однако в списке было еще одно сообщение, которого он пока не видел и которое никогда не смог бы объяснить. Дрожащей рукой он дал команду вывести на экран последнее сообщение. ОБЪЕКТ: ДЭВИД БЕККЕР - ЛИКВИДИРОВАН Коммандер опустил голову. Его мечте не суждено сбыться.

 Конечно, я буду счастлив тебе заплатить.  - И он начал отсчитывать купюры. Глядя, как он шелестит деньгами, Меган вскрикнула и изменилась в лице, по-видимому ложно истолковав его намерения. Она испуганно посмотрела на вращающуюся дверь… как бы прикидывая расстояние. До выхода было метров тридцать.

 Ты явно не в себе, - как ни в чем не бывало сказал Хейл.  - Какие-нибудь проблемы с диагностикой. - Ничего серьезного, - ответила Сьюзан, хотя вовсе не была в этом уверена. Следопыт задерживается. Она подумала, не ошиблась ли где-то. Начала просматривать длинные строки символов на экране, пытаясь найти то, что вызвало задержку.

Подобно киноперсонажу, в честь которого он и получил свое прозвище, его тело представляло собой шар, лишенный всякой растительности.

Он не мог пока ее отпустить - время еще не пришло. И размышлял о том, что должен ей сказать, чтобы убедить остаться. Сьюзан кинулась мимо Стратмора к задней стене и принялась отчаянно нажимать на клавиши. - Пожалуйста, - взмолилась. Но дверца не открылась.
