Sensitive index of cardiac function
The long axis dimension of a mouse heart is approximately 6–8 mm and heart rates usually vary between 400 and 600 beats/min. Therefore, cardiac imaging has to be performed using a high spatial and temporal resolution to allow for quantitative investigation of cardiac volumes and function. On a most basic level the Cardiac Output is a generic proxy for total cardiac function. In a resting individual the average cardiac output is roughly 5000mL/min. Derivation: Cardiac Output = Stroke Volume x Heart Rate When cardiac output is expressed in this way, it is termed " cardiac index " and has the units of L/min/m 2. The surface area is estimated from calculations based on body weight and height. Cardiac index normally ranges from 2.6 to 4.2 L/min/m 2. The PiCCO transpulmonary thermodilution technique provides two indices of cardiac systolic function, the cardiac function index (CFI) and the global ejection fraction (GEF). Both appear to be correlated with left ventricular ejection fraction (LVEF) measured by echocardiography in patients with circulatory failure, especially in septic shock. Neural and endocrine controls are vital to the regulation of cardiac function. In addition, the heart is sensitive to several environmental factors, including electrolytes. Resting Cardiac Output. Cardiac output (CO) is a measurement of the amount of blood pumped by each ventricle in one minute. The ratio of the index of cardiac output to the index of the GEDV. A measure of how well the CO is doing in relation to its preload. Calculates cardiac output, cardiac index, and stroke volume. Inpatients with suspected cardiogenic shock and a pulmonary artery catheter in place. For patients undergoing right or left heart catheterization to determine cardiac output (CO), cardiac index (CI), and stroke volume (SV). The two most widely used ways of calculating CO are Fick’s

Cardiac index normally ranges from 2.6 to 4.2 L/min/m2 in adults at rest. Causes of low cardiac index. Certain conditions which reduce the pumping ability of the heart will result in a lowered cardiac index. Myocardial infarction, or heart attack, heart failure, cardiogenic shock and cardiomyopathy are all conditions in which heart muscle is
CO is a measurement of cardiac function It can be used to assess the degree of cardiac compromise and response to therapies It is the amount of blood ejected by the left ventricle per min It is determined by heart rate x stroke volume . STROKE VOLUME Amount of blood ejected from the heart with each contraction
This classification illustrates the crucial role of cardiac catheterisation in RAP, but the specificity and sensitivity of these indices over a large RAP range are still
22 Feb 2018 A ) Hypertrophy index expressed as heart weight to tibia length was increased in vehicle-treated dTGR compared with SD rats. Treatment with Evaluation of cardiac function is indispensable for the diagnosis and treatment of any cardiovascular disease. In particular, the echocardiographic indexes of cardiac func- tion have been commonly used because they allow simple, accurate, reproducible, and noninvasive evaluation.
14 Sep 2019 PiCCO is a cardiac output monitor that combines pulse contour extravascular lung water (EVLW) which is a sensitive indicator of pulmonary oedema. systemic vascular resistance (SVR), and cardiac function index (CI).
