Our heart is like a double pump mechanism where the right side pumps deoxygenated blood to our lungs and the left side pumps oxygen rich blood to circulate back through our bodies. This process provides a continuous supply of oxygen and eliminates carbon dioxide waste from our body. When there is a disturbance to this process, it causes our heart the inability to pump sufficiently to meet our body’s demands. This causes the body to accumulate blood and fluid in the organs and tissues and will lead to impaired circulation or congestive heart failure. Congestive heart failure is not only the inability to maintain the adequate oxygen delivery; it’s also systemic in attempting to compensate for inadequacy. In general, there have been many great …show more content…

The left side ventricle strength fails to pump enough blood to the body known as cardiac output and backs up into the lungs. This is due to an enlarged ventricle or damaged cardiac muscle. The diastolic failure of left ventricle is the stretching and filling where the ventricle cannot pump the same percentage of blood that is being ejected at each contraction causing it not to stretch enough take to the aorta. Consequently, right side failure is when the ventricle cannot pump its diastolic filling volume into the pulmonary artery, which causes oxygenation problems. Usually this results from left side lung disease such as COPD and fibrosis. As we know, pulmonary disease impairs the exchange of carbon dioxide and oxygen in the alveoli which leads to increase carbon dioxide in the blood. When this happens, we experience pulmonary arterial vasoconstriction resulting in hypertension. The right ventricle is pumping at an increased workload and leads to failure. The right ventricle fails to empty completely and blood is then trapped in the venous vascular system. Thus, the outcome of decreased cardiac output is congestive heart
