Cardiovascular Case Study
Atrial Septal Defect(ASD) is a very large problem concerning the heart in its overall function. When the heart, being the core of the cardiovascular system, has issues; it effects the rest of the body as a result. The core of the problem resides in the atrial septum. Normally the heart is divided into four separate chambers. But a person with atrial septal defect has an atrial septum that allows the blood from the left side of the heart back into the right side. This results in increased pulmonary blood flow and diastolic overload of the right ventricle. By having this constant left-to-right shunt, it can alter the pulmonary vascular resistance leading to hypertension or even the reversal of the shunt itself. There are three types of Atrial Septal Defects: ostium secundum, ostium primum, and sinus venosus. The opening of the atrial septum may be small, on the count of the foramen ovale failing to close; or large, when the septum is completely absent from the heart itself.
There is a very logical explanation between Ryans inability to gain weight, as well as not taking an interest in food during meals. His body isn't able to grow normally because the exchange of nutrients and waste products in his body is completely deficient. He isn't absorbing the adequate amount of nutrients that his body needs. Him being 11-months old, this causes a huge problem because nutrition is extremely important. His heart is working less efficiently, which makes the blood traveling throughout his body subsequently deficient as well. All of the systems in Ryans body are going to be affected by his diagnosis of Atrial Septal Defect.
Ryans growth and development is not appropriate for his age. Ryan was born weighing 7lbs, and now, 11 months later he is 15.4 lbs. He is close to being a 1 year old, and his birth weight should be a little less that triple the amount that he was at birth. Ryan should be approximately 21 lbs at his current age, leaving about...
