The left side of the heart receives blood from the lungs. Whatever comes into the lungs it goes to the heart. It goes to the left artrium then pass to the mitral valve to the left ventricle then the blood pump out to the system. However, the right side of the heart pumps the blood to the lungs. What happen if the left side of the heart is unable to pump out the blood to the system? Or what happen if the left ventricle is tired and can’t do it anymore? The left side of the lungs will go on strike. What happen is the blood backs up to the lungs and the lungs don’t know any better on what to do. The left side of the heart also doesn’t know any better so it keeps on pumping blood to the lungs and lungs to the heart and keeps on pumping. The heart will not take any blood anymore so the blood backs up to the lungs then fluid overload occurs.
In left sided heart failure there is a pulmonary problem. The signs and symptoms are: shortness of breath, fluid overload, pink frothy sputum, and easy fatigability.
