Which is very bad news in a world already and increasingly subject to extreme climatic events. The state of our soils will play an important role in whether we can mitigate and buffer the effects of this climate chaos. Fertile soil is a potentially vast carbon sink, second only to the worldâs oceans.
Quick Answer. Ejection fraction normally refers to measurements related to the left ventricle of the heart, and patients with an ejection fraction between 55 and 70 percent are in the normal range, notes Cleveland Clinic. Ejection fraction measures how much blood is pumped from the patient's left ventricle during heart contractions. Keep Learning.
The ejection fraction is a useful measure of left ventricular performance. The normal range is 63-77% for males and 55-75% for females (reference: Measurements in Cardiology). If the left ventricle wall is thinned, a decrease in the ejection fraction is seen.We can use computer programs in the cath lab to calculate the EF, if we do a left ventriculogram, and then trace the end systolic and end diastolic outlines.f the left ventricle wall is thinned, a decrease in the ejection fraction is seen.
