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, or EF, is a measurement that indicates how well your heart is functioning. This number tracks how much blood your heart is pumping out with each contraction. Your ejection fraction is described as a percentage. If youâre healthy, your ejection fraction is generally between 55% and 70%. For instance, an ejection fraction of 60% means your heart is pumping 60% of your blood out of your left ventricle (its main pumping chamber) every time your heart beats.
