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.
Or the HFS (Heart Falure Society}; The ejection fraction is a measurement of how well the heart is pumping. People with a healthy heart have an EF of about 60 percent, while people with heart failure have an EF of 40 percent or less. In any case the OP does not have heart failure by definition. Ejection fraction (EF): a measurement of the amount of blood pumped out of the left ventricle with each heartbeat.
