Cardiac function curve — A cardiac function curve is a graph showing the relationship between right atrial pressure (x axis) and cardiac output (y axis). Shape of curve It shows a steep relationship at relatively low filling pressures and a plateau, where further stretch … Wikipedia
Cardiac output — (Q or or CO ) is the volume of blood being pumped by the heart, in particular by a left or right ventricle in the time interval of one minute. CO may be measured in many ways, for example dm3/min (1 dm3 equals 1000 cm3 or 1 litre). Q is… … Wikipedia
