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.
Ejection fraction is a term that describes the ability of the heart to pump out blood, which is compromised in a person with congestive heart failure. Essentially, ejection fraction is a measurement of the relative strength or weakness of a person's heart. The lower the ejection fraction, the more difficulty the heart has in pumping blood from the left ventricle. A normal ejection fraction may be in the range of 50-75%. Anything below 50% is generally indicative of chronic, or congestive, heart failure.
