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.
As not all of the blood is ejected from the heart with the contraction of the ventricles, the âejection fraction is the amount that is ejected after the ventricle is filled. The main ventricle of the heart valve is the left ventricle, the ejection fraction of the heart is measured here. Therefore, it can be stated that the normal range for the left ventricle (LV) ejection fraction is 55 to 70 percent. slide 2 of 4.
