Valves

Physiology Murmurs are the product of intense blood flow across inflexible, calcified valves; faulty valves that permit reverse blood flow (regurgitation); faulty (deviant openings) in the septum, aorta, or pulmonary artery; or abnormally high velocity of blood flow through a normal structure. Supposedly blood generally flows soundlessly through the heart; yet, these conditions can generate tumultuous blood flow resulting in auscultation of swooshing or gusty sound over the precordium (Weber &…

consists of three covers: a cover of tissue on the outside, a cover of smooth epithelial cells on the inside and a cover of muscle in between. Veins transfers’ blood to the heart and lungs at low pressure afterward getting it from the capillaries. The valves are found inside the veins and make keep blood moving in one direction. Capillaries attach veins and arteries to swap oxygen and carbon dioxide. It is slim and wobbly. The capillaries are just as fat as one epithelial cell. Blood passes over…

the right atrium contracts and pumps its contents into the right ventricle through the tricuspid valve. Once the right atrium is drained completely, the tricuspid valve will close to prevent blood from flowing back into the right atrium. Next, the right ventricle contracts, causing the pulmonary valve to open and forcing blood into the pulmonary artery. Once the blood is emptied, the pulmonary valve will close to prevent backflow. The deoxygenated blood will travel to the lungs through the…

view is completed the left ventricle (LV), mitral valve and the mitral valve apparatus, the left atria (LA), left ventricular outflow, and the aortic valve (AV) are visualized (Fridman, Finkielstein, 2013). A TTE provides valuable information for determining the size and shape of the heart, the strength of pump, location of tissue damage, and determine if there any change in the pattern of blood flow. It is able to visualize all of the heart valves determine thickening, and calcific changes…

heart. These include defective heart valves, hypertrophic cardiomyopathy (enlarged heart muscle), holes or abnormal openings in the walls of the heart (septal defects), aortic aneurysm, or other congenital heart disease. This causes blood flow into the heart to be really slow and does not allow the affected person to live a long healthy life. Treatment of heart murmurs If a septal defect is causing the heart murmurs, corrective surgery may be required. If heart valve disease is causing the…

blow tube and in the pipe connecting blow tube and air reservoir. Fig. 3 Variation of air pressure with time in the blow tube. This peak pressure is observed at 8.8 ms after the actuation of the valve. It means that valve will be fully opened at 8.8 ms after the actuation. Since the time period of valve opening is 150 ms, it is clear that there is a mechanical…

the Unloading valve is pressure-control devices that are used to dump excess fluid to tank at little or no pressure, Therefore, if this valve does not work it is function probably, it will cause problem. For example, the two position direction valve remained in close position (no fluid flow to the tank) due to many factors such as no PLC signal received, pressure switch is out of order, blockage in the pilot line between the pressure switch and two position direction valve, pressure…

Some people are born with abnormalities of their valves, may even be born with a murmur; those people are likely to need surveillance through their lives because those valves can deteriorate. Other people can acquire minor valve abnormalities, one instance would be due to endocarditis, and those people need ongoing surveillance during their lives. So those are givens, they should be following regular medical surveillance with their doctor and paying attention to their body. How do we address…

“A heart murmur is an extra or unusual sound heard during a heartbeat. Murmurs range from very faint to very loud. Sometimes they sound like a whooshing or swishing noise.” (National Institute of Health). Heart murmurs originate from the heart, causing an abnormal beating of the heart. They can be heard by the individual, making turbulent and rushing sounds. “A thrill by definition is a palpable murmur, so the term “palpable thrill” is redundant. A thrill should be identified as present or…

What is Cardiovascular Disease? (Heart & Blood Vessels) A heart and blood vessel disease (heart disease) is multiple problems within the heart one major one is called atherosclerosis. Atherosclerosis is a heart condition caused by a substance called plaque that build up on the walls of the heart arteries. This plaque buildup can narrow the hearts arteries making it harder for blood to flow through. When this problem starts to happen it can cause clotting which is able to stop blood flow and…
