    Cardiac output - Wikipedia

    • In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , , or , is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured per minute). Cardiac output (CO) is the product of the heart rate (HR), i.e. the number of heart… 展开

    Definition

    The function of the heart is to drive blood through the circulatory system in a cycle that delivers oxygen, nutrients and chemicals to the body's cells and removes cellular waste. Because it pumps out whatever blood comes bac… 展开

    Measurement

    There are a number of clinical methods to measure cardiac output, ranging from direct intracardiac catheterization to non-invasive measurement of the arterial pulse. Each method has advantages and drawbacks. Relative compari… 展开

    17.4E: Cardiac Output - Medicine LibreTexts

    Cardiac output, a measure of how much blood the heart pumps over the course of a minute, is calculated by multiplying heart rate by stroke volume. The heart rate is increased by sympathetic nervous stimulation and decreased by …

    Stroke volume, ejection fraction, and cardiac output

    The ejection fraction is the proportion of the end-diastolic volume that is pumped out with each beat. It is calculated as stroke volume divided by the end-diastolic volume. Cardiac output is the amount of blood the heart pumps in one minute …

    Cardiac output - wikidoc

    Cardiac output (CO) is defined as the amount of blood pumped by the left ventricle in unit time. CO = Stroke Volume x Heart Rate. Therefore, if there are 70 beats per minute, and 70 ml blood is ejected with each beat of the heart, the …
