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 (EF) is an important measurement in determining how well your heart is pumping out blood and in diagnosing and tracking heart failure. A significant proportion of patients with heart failure happen to have a normal ventricular ejection fraction at echocardiography during examination. Previously called diastolic heart failure, it is now referred to as heart failure with normal ejection fraction (HFNEF) or HF with preserved ejection fraction.
