WebFeb 17, 2024 · Ejection fraction is a measurement of the percentage of blood leaving the heart each time it squeezes. When the heart squeezes, it's called a contraction. Ejection fraction is just one of many tests your health care provider may use to see how your heart works. The heart contracts and relaxes. WebCardiac output curves for the normal heart and for hypoeffective and hypereffective hearts. Point A on the normal cardiac output curve denotes resting cardiac output (5 l/min at a right atrial pressure of 0 mmHg). Several other curves are also depicted for hearts that are not pumping normally. WebCardiac output (CO) is rarely monitored during surgery, and arterial pressure remains the only hemodynamic parameter for assessing the effects of volume expansion (VE). However, whether VE-induced changes in arterial pressure accurately reflect changes in CO has not been demonstrated. fbi and my pillow
