A System for Continuous Estimating and Monitoring Cardiac Output via Arterial Waveform Analysis
Background: Cardiac output (CO) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. CO is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. Hence, measuring CO has always been a matter of interest to researchers and clinicians. Sev...
متن کاملRelation of effective arterial elastance to arterial system properties.
Effective arterial elastance (E(a)), defined as the ratio of left ventricular (LV) end-systolic pressure and stroke volume, lumps the steady and pulsatile components of the arterial load in a concise way. Combined with E(max), the slope of the LV end-systolic pressure-volume relation, E(a)/E(max) has been used to assess heart-arterial coupling. A mathematical heart-arterial interaction model wa...
متن کاملFusiform aneurysm of the vertebrobasilar arterial system.
We retrospectively evaluated the clinical features and therapeutic outcomes in 13 consecutive patients with the diagnosis of fusiform aneurysm of the vertebrobasilar system. Four patients (31%) presented with compressive symptoms and 10 (77%) with ischemic symptoms; one patient presented with both types of symptoms. No patient presented with rupture of the fusiform aneurysm. Based on the attend...
متن کاملMicroangiography of the Pulmonary Arterial System
Microanigiographlic examinatioin of the pulmoniary arterial svstem in 12 n1ewborn in1fants with conicomitanit steniosis or atresia of the aortic anid mitral orifices showed that the intrapulmonary arterial pattern is inifluenced by the state of the forameni ovale. In inifanlts with aortic atresia with a prematuirely closed foramein ovale, that is cases in which the left side of the heart is a c...
متن کاملA simple model for the arterial system.
We present a simple model for the arterial part of the cardiovascular system, based on Poiseuille flow constrained by the power dissipated into the cells lining the vessels. This, together with the assumption of a volume-filling network, leads to correct predictions for the evolution of vessel radii, vessel lengths and blood pressure in the human arterial system. The model can also be used to f...
