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 - Explanation of Normal and Abnormal Range. Ejection Fraction (EF) is one of the measurements used by physicians to assess how well a patient's heart is functioning. Ejection refers to the amount of blood that is pumped out of the heart's main pumping chamber during each heartbeat. Fraction refers to the fact that, even in a healthy heart, some blood always remains within this chamber after each heartbeat.
