Because of this inability to contract effectively, the rest of the vital organs receive inadequate amount of blood resulting to inadequate tissue perfusion. There are two types of left-sided HF; systolic and diastolic failure. Systolic failure happens when the left ventricle doesn’t have the enough energy to pump normally the blood to the general circulation. As for diastolic failure, the left ventricle loses the ability to fill itself with blood during resting period resulting to inadequate amount of blood to be pumped out to the circulation (Weinrauch, 2008). The diastolic dysfunction will eventually lead to right-sided heart failure.

It affects premature infants because their lungs not fully develop and the lungs don’t have an insufficient surfactant. The surfactant is a complex phospholipid+ protein secreted by type 2 cell. It reduces surface the tension of alveolus. It keeps the alveoli open and prevents a collapse of the alveoli. When the surfactant is inadequate the alveoli will collapse, lung expansion will become more difficult ( compliance).

Also how technology and time have made this procedure much tranquil. So what is it? Cyanosis is a condition in which a bluish color is seen in the skin due to lack of oxygen to the blood. Cyanosis can be caused by many complications in the heart. In other words something is not working in the plumbing

Normally blood entering the right side of the heart stays on the right side (this is low-oxygen blood), and blood on the left side of the heart stays on the left side (this is oxygen-rich blood) which is then pumped to the rest of the body. But in this particular condition when a defect or "hole" is present between the ventricles (or lower chambers), blood from the left side of the heart is forced through the defect to the right side every time the heart beats. It then goes back to the lungs even though it is already rich in oxygen. Because of this, blood that is not yet oxygen-rich can 't get to the lungs. The most common signs and symptoms are trouble eating and gaining weight, breathlessness and easy fatigability in

“An average heart has four chambers; two upper, called the atria and two lower, called the ventricles. The right side of the heart receives blood that is returning from the body. This oxygen-lacking blood arrives in the right atrium, where it is pumped into the right ventricle. The right ventricle sends the blood to the lungs, where it is picks up plenty of oxygen. This oxygen-rich blood then enters the left atrium and is pumped into the left ventricle, which pumps blood through the aorta to all the organs and tissues of the body” (Blaser).

Also, that it is a failure to the cardiovascular system in which the blood circulation decrease and eventually ceases. The second thing I learned, is that shock can be both cardiovascular and non-cardiovascular. Three major cardiovascular causes of shock are: poor pump function blood or fluid loss from blood vessels and poor vessel function. The third thing i learned was the progression of shock. When checking for shock, shock itself can not be seen, but the signs and symptoms can be.

Underlying theory: • Circulatory system theory: It is the body’s main transport system, the system is made up of the heart, the blood and the blood vessels. The blood transports oxygen, carbon dioxide, hormones and nutrients, . The circulatory system is a closed system which means that blood flows around the body enclosed in blood vessels and does not leave the blood vessels. The heart: The heart consists of many layers: 1. The pericardium- It has two layers.

The Pintails heart is like a mammals consisting of four chambers, two ventricles and two atria. The left ventricle pumps blood to all major organs in the body and throughout the rest, only excluding the lungs. This causes the left ventricle to be larger and more muscular. The lungs are fed blood from the right ventricle, which is the only the only function of that ventricle. The oxygenated blood coming from the lungs is fully separated from the oxygenated blood coming from other parts of the body.

They both have c-shaped cartilage. There are no cartilage structure on the bronchioles. The main function of the bronchi and bronchioles is to carry oxygen from the trachea into the lungs. Smooth muscle is located within the walls to help control airflow into the lungs. At the end of each bronchiole is alveoli.

Perfusion : Perfusion is the process of a body delivering blood to a capillary bed in itsbiological tissue. The word is derived from the French verb "perfuser" meaning to "pour over or through"[3]. Tests verifying that adequate perfusion exists are a part of a patient's assessment process that are performed by medical or emergency personnel. The most common methods include evaluating a body's skin color, temperature, condition and capillary refill. Perfusionists employ artificial blood pumps to propel open-heart surgery patients' blood through their body tissue, replacing the function of the heart while the cardiac surgeon operates.
