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

Blood pressure measurement

This study aimed to quantify blood pressure BP measurement accuracy and variability with different techniques. Ten observers without receiving medical training were asked to determine BPs using a traditional manual auscultatory method and b visual auscultation method by visualizing the Korotkoff sound waveform, which was repeated three times on different days. The measurement error was calculated against the reference answers, and the measurement variability was calculated from the SD of the three repeats. Statistical analysis showed that, in comparison with the auscultatory method, visual method significantly reduced overall variability from 2. It also showed that BP measurement errors were significant for both techniques all , except DBP from the traditional method. In conclusion, the visual auscultation method had the ability to achieve an acceptable degree of BP measurement accuracy, with smaller variability in comparison with the traditional auscultatory method.

Exploratory Study. METHODS: A questionnaire with 5 questions about practices and behaviors regarding blood pressure measurement and the diagnosis of hypertension was sent to 25, physicians in all Brazilian regions through a mailing list. The responses were compared with the recommendations of a specific consensus and descriptive analysis. The following items were reported: use of an aneroid device by For hypertension diagnosis, The results suggest that, to include the great majority of the medical professionals, disclosure of consensus statements and techniques for blood pressure measurement should go beyond the boundaries of medical events and specialized journals. Blood pressure measurement with the indirect method with the auscultatory technique is the most frequently used procedure in clinical practice for the diagnosis of arterial hypertension and assessment of the efficacy of treatment.

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. Diastolic pressure is minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood. Systolic and diastolic arterial blood pressures are not static but undergo natural variations [2] 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.

Principles and techniques of blood pressure measurement.

Measurement of blood pressure is an important diagnostic and monitoring procedure. Blood pressure measurement is a common diagnostic and monitoring procedure, and accuracy is essential if patients are to receive the appropriate treatment and care in a timely manner. This article, part 1 in a two-part series, discusses principles of blood pressure monitoring and the devices used. Part 2 will describe the procedures for monitoring blood pressure.

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.
