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 کاملBioreactance is a reliable method for estimating cardiac output at rest and during exercise.
BACKGROUND Bioreactance is a novel noninvasive method for cardiac output measurement that involves analysis of blood flow-dependent changes in phase shifts of electrical currents applied across the thorax. The present study evaluated the test-retest reliability of bioreactance for assessing haemodynamic variables at rest and during exercise. METHODS 22 healthy subjects (26 (4) yrs) performed ...

متن کاملMeasurement of Cardiac Output using Bioimpedance Method
Cardiac output (CO), in conjunction with hemoglobin concentration and arterial oxygen saturation are the cornerstones of oxygen transport. Cardiac output is the functional expression of cardiovascular performance and can be used to confirm the need for, or usefulness of treatment. Determination of cardiac output is an important procedure in interventional cardiology and also used in cardiothora...
متن کاملTransthoracic echocardiography: an accurate and precise method for estimating cardiac output in the critically ill patient
BACKGROUND Cardiac output (CO) monitoring is a valuable tool for the diagnosis and management of critically ill patients. In the critical care setting, few studies have evaluated the level of agreement between CO estimated by transthoracic echocardiography (CO-TTE) and that measured by the reference method, pulmonary artery catheter (CO-PAC). The objective of the present study was to evaluate t...
