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.
An ejection fraction of 60% means that 60% of the total amount of blood in the left ventricle is pushed out with each heartbeat. What's normal? A normal heart's ejection fraction may be between 50% and 70%. You can have a normal ejection fraction reading and still have heart failure (called HFpEF or heart failure with preserved ejection fraction).
