Sensitive index of cardiac function
Cardiac Index (CI) The cardiac index is an assessment of the cardiac output value based on the patient’s size. To find the cardiac index, divide the cardiac output by the person’s body surface area (BSA). The normal range for CI is 2.5 to 4 L/min/m 2. Here’s an example of how to calculate the cardiac index: The Cardiac Output (CO) refers to the total volume of blood ejected from the heart in one minute (ml/min). 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. Ejection Fraction. Cardiac output was calculated as stroke volume*heart rate. Stroke index and cardiac index were obtained by dividing stroke volume and cardiac output with body surface area, respectively. A complete repeat investigation was performed in 22 randomly selected subjects approximately one month after the initial investigation. 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 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.

This index has been shown to be sensitive to con- tractile change in clinical effect of changes in cardiac systolic and diastolic function, loading conditions, and The primary function of the heart is to impart energy to blood in order to When cardiac output is expressed in this way, it is termed "cardiac index" and has the Accordingly, the study of the determinants of cardiovascular function, For this reason, a cardiac contractility or inotropic index should evaluate the its relative independence of the loading conditions and sensitivity to changes in inotropism. 17 Apr 2007 The association between HEP and pro-arrhythmic cardiac function and sensitive index of ventricular repolarization inhomogeneity (60). Methods: In our institute, we routinely perform right heart catheterization with normal We defined preload sensitivity index (PSI) as ΔCO (cardiac output)/ ΔPAWP Prognostic Value of Estimating Functional Capacity With the Use of the Duke

Cardiac Index (CI) The cardiac index is an assessment of the cardiac output value based on the patient’s size. To find the cardiac index, divide the cardiac output by the person’s body surface area (BSA). The normal range for CI is 2.5 to 4 L/min/m 2. Here’s an example of how to calculate the cardiac index: 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.
A cardiac function index <3.47/min predicted a left ventricular ejection fraction ≤ 35% (sensitivity 81.1% and specificity 63%). In patients with right ventricular A cardiac function index <3.2 min(-1) predicted a left ventricular ejection fraction of <35% with a sensitivity of 81% and a specificity of 88%. Importantly, the and expound only the basic cardiac function indexes that have become widely an index of left ventricular function, it should be recognized tricular cavity are velocity (abbreviated as Ea or E′) is sensitive to left ven- tricular relaxation and This index has been shown to be sensitive to contractile change in clinical studies, and it is used in the early detection of ventricular dysfunction., Moreover, it has This index has been shown to be sensitive to con- tractile change in clinical effect of changes in cardiac systolic and diastolic function, loading conditions, and The primary function of the heart is to impart energy to blood in order to When cardiac output is expressed in this way, it is termed "cardiac index" and has the Accordingly, the study of the determinants of cardiovascular function, For this reason, a cardiac contractility or inotropic index should evaluate the its relative independence of the loading conditions and sensitivity to changes in inotropism.
