What is Cholesterol?Cholesterol is a sterol (a combination steroid and alcohol). Cholesterol is a lipid found in the cell membranes of all tissues, and it is transported in the blood plasma of all animals. Because cholesterol is synthesized by all eukaryotes, trace amounts of cholesterol are also found in membranes of plants and fungi.The name originates from the Greek chole- (bile) and stereos (solid), and the chemical suffix -ol for an alcohol, as researchers first identified cholesterol in solid form in gallstones by Francois Poulletier de la Salle in 1769. However, it is only in 1815 that chemist Eugene Chevreul named the compound "cholesterine".[2]Most of the cholesterol is synthesized by the body and some has dietary origin. Cholesterol is more abundant in tissues which either synthesize more or have more abundant densely-packed membranes, for example, the liver, spinal cord and brain. It plays a central role in many biochemical processes, such as the composition of cell membranes and the synthesis of steroid hormones. Cholesterol is insoluble in blood, but is transported in the circulatory system bound to one of the varieties of lipoprotein, spherical particles which have an exterior composed mainly of water-soluble proteins. The main types, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) carry cholesterol from and to the liver.According to the lipid hypothesis, abnormally high cholesterol levels (hypercholesterolemia) and abnormal proportions of LDL and HDL are associated with cardiovascular disease by promoting atheroma development in arteries (atherosclerosis). This disease process leads to myocardial infarction (heart attack), stroke and peripheral vascular disease. As high LDL contributes to this process, it is termed "bad cholesterol", while high levels of HDL ("good cholesterol") offer a degree of protection. The balance can be redressed with exercise, a healthy diet, and sometimes medication. |

Measuring the Blood Pressure Techniques of measurement. Rough estimates without using any equipment at all. It is not possible to derive a numerical value for blood pressure without ABC of hypertension: Blood pressure measurement -- Beevers et al The measurement of blood pressure in clinical practice by the century-old technique of Riva-Rocci/Korotkoff is dependent on the accurate transmission and ABC of hypertension: Blood pressure measurement -- Beevers et al The array of techniques available today owe their origins to the conventional technique of auscultatory blood pressure measurement, and these new techniques Blood pressure - Wikipedia, the free encyclopedia Arterial blood pressure (BP) is most accurately measured invasively. Invasive arterial pressure measurement with intravascular cannulae involves direct Accuracy of Blood Pressure Measurement Background: Equipment, physiologic, and technique factors can influence the accuracy of blood pressure measurement. The current study was designed to Recommendations for Blood Pressure Measurement in Humans 16 The oscillometric technique has been used successfully in ambulatory BP . Task Force II: blood pressure measurement and cardiovascular outcome. Method for the measurement of the blood pressure Many devices and in particular the automatic devices measuring the blood pressure during 24 hours, use the two measurement techniques. Oscillometric method Recommendations for blood pressure measurement in humans and For accurate blood pressure measurement, the observer must: (1) be properly trained in the techniques of blood pressure measurement; (2) use an accurate and 3. Blood pressure measurement Before the blood pressure measurement begins the following conditions should be . test that could be based on similar techniques as the training methods, The impact of blood pressure measurement methods on the assessment The aim of the study was to investigate the impact of various blood pressure (BP) measurement methods on the assessment of differences in BP levels between Evaluating indirect blood pressure measurement techniques: a Evaluating indirect blood pressure measurement techniques: a comparison of three systems in infants and children. RF Reder, I Dimich, ML Cohen, L Steinfeld Ultrasonic Investigation Of The Indirect Blood Pressure imaging technique which facilitates investigation of the. physiological basis for the indirect blood pressure (b.p.). measurement procedure. Evaluation of a Direct Blood Pressure Measurement Technique for use of the central ear artery blood pressure. measurement technique in canine toxicity .. of noninvasive blood pressure measuring techniques. Toxicol. IngentaConnect Nurses knowledge of error in blood pressure Errors arise from faults in measurement technique or the equipment used. In Australia, blood pressure measurement technique is taught to nurses during their Noise-immune blood pressure measurement technique and system An apparatus and method for non-invasive, noise insensitive blood pressure determination which is useful in a battlefield or emergency vehicle environment. GUIDELINE 3: MEASUREMENT OF BLOOD PRESSURE IN ADULTS SMPB devices142 are varied in design from manual to fully automated and in blood pressure measurement technique (mercury, aneroid, oscillometric). Proper Technique for Blood Pressure Measurement - How to Measure The ability to correctly measure blood pressure is a specialized skill that requires careful attention to many important details. A wide variety of factors Recommendations for Blood Pressure Measurement in Humans and Identification and evaluation of noninvasive blood pressure measuring techniques.
