Presentation of a Non-invasive Method of Estimating Arterial Stiffness by Modeling Blood Flow and Arterial Wall Based on the Determination of Elastic Module of Arterial Wall
Introduction: Arterial stiffness is an important predictor of cardiovascular risk. Several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. Since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...
متن کاملArterial stiffness: reflections on the arterial pulse.
Arteriosclerosis—arterial stiffening—is the basic cause of isolated systolic hypertension (ISH) and the present epidemic of heart failure in the elderly. Arteriosclerosis is equally important for the development of coronary events, stroke, dementia, and renal failure. The underlying pathology was described by Osler as ‘senile arteriosclerosis’ to distinguish it from essential hypertension (Osle...
متن کاملPropagation of Blood Flow Pulse in the Normal Human Pulmonary Arterial System
We studied a number of dynamic events associated with the pulsatile flow of blood in the pulmonary arterial system of six healthy men in the supine position. We used the nitrous oxide-body plethysmograph method to record the pulmonary capillary blood flow pulse and the phonocardiogram to determine the time of opening and closing of the pulmonary valve. The pattern of right ventricular ejection ...
متن کاملPulse pressure, blood flow, and atherosclerosis.
B lood vessels are exposed to two kinds of dynamic mechanical forces. One of them is shear stress and the other is the cyclic strain of the vascular wall, which, according to the Laplace’s law, is mainly determined by cyclic change of blood pressure (BP). While shear stress directly affects endothelial cells, BP changes (and the resulting changes in arterial wall strain) influence all structure...
متن کاملInterpretation of Arterial Blood Gas
تجزیه و تحلیل گازهای خون اطلاعات مهمی را در مورد اکسیژناسیون شریانی و تعادل اسید - باز در دست ما قرار می دهد. در ک این داده ها بخشی اساسی از مراقبت پرستاری در اکثر بیماران است. هنوز برای بسیاری از پرستاران، تفسیر نتایج گازهای خون شریانی همانند یک جدول پیچیده بوده و در مواقعی که بررسی تمام نتایج در اسرع وقت مورد نیاز باشد، این مشکل بیشتر نمایان می شود.
