1. Capillary blood pressure was measured in man using a dynamic servo-nulling system and direct micropuncture. This enabled assessments of the normal variations in pressure which influence fluid filtration and reabsorption. 2. Seventy-eight capillaries in 19 subjects were punctured in one of three positions around the capillary loop with the hand at the level of the sternal angle. Mean pressure...

Riva-Rocci Korotkoff (RRK) blood pressure measurements may overestimate the intra-arterial pressure (IAP) in individual patients. To study pseudohypertension, defined as an overestimation larger than 10 mm Hg, we compared RRK and IAP measurements in 76 patients. These patients were considered to be at risk for pseudohypertension because of high age, hypertension, or vascular disease. RRK measur...

The value of measuring blood pressure in the clinic is debatable, especially when it is done by doctors. Inherent variability means that true changes in blood pressure can be difficult to detect using clinic readings. Furthermore, misclassification on the basis of clinic readings can occur in people with “normal” underlying blood pressure who are labelled as hypertensive because of the pressor ...

In this paper oscillometric method is used to develop an adaptive non-invasive blood pressure measurement system. To overcome the drawback of conventional oscillometric method an algorithm is developed. During the time of deflation and inflation process the step size of pressure pumped and released using pump and valve respectively is varied adaptively by continuously monitoring the feedback wh...

Hypertension, the leading global risk factor for early mortality, cannot be detected or treated without accurate and practical methods of blood pressure (BP) measurement. Although home BP measurement has considerable popularity among patients, the lack of evidence needed to assure its place in modern clinical practice has hindered its widespread acceptance among physicians. This paper demonstra...

Automatic and semi-automatic bloodpressure meters are simple-to-use thus widespread in home health monitoring. However, their results are not accurate and reproducible enough, the reliability of self-assessment is not satisfactory, medical doctors have reservations for the results. The occlusion by the cuff – applied in the majority of indirect bloodpressure meters changes the biomechanical pro...

A number of problems relating to clinic measurements of blood pressure may be particularly relevant to elderly patients with isolated systolic hypertension. First, there are large discrepancies in the blood pressure levels measured by these two techniques in the elderly population. Second, while blood pressure is universally accepted as one of the most important risk factors for the development...

be invaluable. By this period, too, mass production was beginning to shape the face of instruments (are there deep historical relations between mass production and asepsis?). Edmonson takes his story up to 1900 when radical surgery for conservative ends was introduced. By now mass marketing accompanied mass production and the American domestic industry felt the heat of competition, notably from...

Blood pressure self-measurement (BPSM) requires patients to follow a range of recommendations in order to be considered reliable for diagnostic use. We investigated currently used BPSM interventions at four medical clinics combined with an online questionnaire targeting BPSM users. We found that the participating healthcare personnel perceived BPSM as a relevant and useful intervention method p...

The objective of this study is to investigate how blood pressure is measured in different outpatient clinics. This is a retrospective study performed with 1,000 patients, randomly selected among patients followed in different outpatient clinics in Fortaleza, Brazil. Among the 1,000 patients, 962 had available records. The older the patient, the greater the possibility of having had blood pressu...
