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. |

Blood Pressure 2.) Blood pressure can be taken through a thin shirt or blouse rather than having the patient remove it or rolling the sleeve up. 3.) Palpate the brachial ESTIMATION OF THE DIASTOLIC ARTERIAL BLOOD PRESSURE BY PALPATION The fact that the palpatory method of indirect measurement of blood pressure can be used to estimate the diastolic arterial pressure is apparently not Best Practice - Vital Signs A comparison between systolic blood pressure measurements taken by auscultation and palpation found both were within 8 mmHg. While palpation has been Blood Vessels Various facts about human blood pressure for nursing students. to record an approximate value for systolic pressure by palpation, before auscultation, Interpretation - Blood Pressure - Vital Signs In situations where auscultation is not possible, you can determine systolic blood pressure by palpation alone. Inflate the cuff until the pulse disappears. Accuracy of the advanced trauma life support guidelines for We assessed whether the guidelines accurately predict systolic blood pressure by palpation of radial, femoral, and carotid pulses in hypovolaemic patients MoonDragon's Lab Information & Tests - Blood Pressure by Palpation MoonDragon's Lab Information & Tests - Blood Pressure by Palpation. Vital Signs Systolic Pressure - In situations where ausculation is not possible, you can determine systolic blood pressure by palpation alone. Measuring the Blood Pressure If the pulse is palpated as the cuff is being inflated and deflated the blood pressure may be estimated by palpation and reading the cuff pressure on the OPETA: Vital Signs Blood Pressure by Palpation. Accurately select proper cuff size and state reasoning; Correctly place cuff on arm; Support arm at heart level; Palpate radial |
