The Use Of Blood Pressure And The Aortic Stiffness

Abstract The pulsatile component of blood pressure has received notable awareness as an important hazard for cardiovascular disease. To anticipate the cardio vascular events central blood pressure measurement plays an important role. If the blood vessel are of high compliance or low stiffness, the pressure exerted on the walls of blood vessel or arteries during the systole is the lowest. But due to wave reflection, the blood pressure in the upper limb does not provide the central blood pressure. Therefore, modern researchers are deeply interested to find a noninvasive method of measuring central blood pressure and the aortic stiffness.†¦show more content†¦Some researcher has suggested that Pulse wave velocity(PWV) method is the convenient way to measure arterial stiffness. But System for measuring of PWV is not accurate. So therefore, it is necessary to increase accuracy by enlargement of sampling rate and distance between sensors for improving the system so that this could be a useful outcome for diagnostic purpose. However, the time delay between backward and forward waves in the central aorta may lead to the prominent feature of backward waves near central blood pressure. In this review we will conceived the methods for improved PWV estimation from central and peripheral blood pressure. The basic scientific principles of Pulse wave velocity through the arterial tree dates back to 1808 with the work of Thomas Young(an English polymath and physician).The relationship between pulse wave velocity (PWV) and arterial wall stiffness is basically calculated from first principles from Newton s second law of motion; F=ma. In clinical diagnosis, several factors are used to measure the artificial stiffness and it was the European society of hypertension who first recognised that PWV is the integral factor of diagnosis and treatment. Methodology This pressure and flow waves in the blood vessel or arteries are measured by a phase velocity which is known as Pulse Wave Velocity (PWV). PWV is defined as speed of energy wave
