What is pulmonary atresia?
Pulmonary atresia is a congenital heart defect where the pulmonary valve does not form properly, leading to a blockage of blood flow from the heart to the lungs. This condition can result in low oxygen levels in the blood and may require surgical intervention to improve blood flow to the lungs.
What is a Pulmonary embolus?
A pulmonary embolus occurs when a blood clot, usually originating in the leg, travels to the lungs and blocks a pulmonary artery. This can result in symptoms such as shortness of breath, chest pain, and even life-threatening complications if not treated promptly. Treatment typically involves blood thinners and, in severe cases, procedures to remove the clot.
Through what valves must the blood move in order to get into the pulmonary artery?
The blood must flow through the pulmonary valve to reach the pulmonary artery. The pulmonary valve is located between the right ventricle and the pulmonary artery, allowing blood to be pumped out of the heart and into the lungs for oxygenation.
What structures are most closely associated with the transport of deoxygenated blood?
The pulmonary arteries and pulmonary veins are most closely associated with the transport of deoxygenated blood. The pulmonary arteries carry deoxygenated blood from the heart to the lungs for oxygenation, while the pulmonary veins return oxygenated blood from the lungs to the heart.
What are the parts of pulmonary circulation?
Starting from the right atrium, blood flows into the right ventricle then into the pulmonary arteries. The blood branches throughout the pulmonary trunk and down to the level of the pulmonary capillaries. At this level carbon dioxide dissolves out of the blood and the erythrocytes (red blood cells) pick up oxygen. The blood is collected in the pulmonary veins and taken back to the left atrium for distribution throughout the body.
Can a pulmonary embolism burst open?
A pulmonary embolism (PE) itself does not "burst open," as it is a blockage in a pulmonary artery caused by a blood clot or other material. However, if the clot breaks apart or if new clots form, it can lead to further complications, including the obstruction of additional blood vessels in the lungs. This can exacerbate symptoms and increase the risk of serious health issues, such as respiratory failure. Prompt medical attention is crucial to manage and treat a pulmonary embolism effectively.
How is a vain used to bypass a blockage?
The vein is used quite frequently to by pass blockage. The veins are first recovered and prepared by removing any valves. It is then reversed and joined by suturing to the artery above the obstruction and the lower end is joined below the obstruction so that blood can bypass and flow through this new venous channel past the obstruction .
What can precipitation in IV administration lead to?
Precipitation from the solution may lead to complications such as pulmonary microcapillary occlusion and blockage of blood flow.
What is pulmonary atresia?
Pulmonary atresia is a congenital heart defect where the pulmonary valve does not form properly, leading to a blockage of blood flow from the heart to the lungs. This condition can result in low oxygen levels in the blood and may require surgical intervention to improve blood flow to the lungs.
Is the blockage of a vessel by an embolus an embolism?
Yes, an embolism is the sudden blockage of a blood vessel by an embolus. The embolism is often named for the causative factor, such as an air embolism or a fat embolism or its location, such as pulmonary embolism.
Can chrohns disease cause bilateral pulmonary embolisms?
Chron's disease is a chronic inflammation of the large intestine, and pulmonary embolism is a blockage of blood-flow in the lungs. There is nothing I can think of that Chron's disease would put in the bloodstream that would block blood flow to the lungs; so i am inclined to say no.
What is a traveling blood clot called?
A traveling blood clot is called an embolus. It can move through the bloodstream and potentially get lodged in a blood vessel, causing blockage and leading to serious health complications such as a pulmonary embolism or stroke.
What is the difference between cor pulmonale and pulmonary embolism?
A pulmonary embolism is a tissue fragment (part of a blood clot, fat, amniotic fluid, part of a tumour or bullet fragment) that became loose in the blood stream and was carried by the blood stream to a different location. A pulmonary embolism is, in most cases, a thromboembolism (part of a blood clot), which is carried from the deep veins of the legs or the pevis. It travels up the blood stream, through the inferior vena cava, into the heart, and subsequently into the pulmonary artery. In the pulmonary artery, it arrests, forming a potentially life threating occlusion. Cor pulmonale is hypertrophy of the right ventricle due to chronic pulmonary hypertension. The pulmonay hypertension means that the right ventricle has to pump blood with greater force, causing its muscle to hypertrophy (enlarge in size). Therefore, to summarize, a pulmonary embolism is an obstruction of pulmonary blood flow while cor pulmonale is the morphological change of the right ventricle due to pulmonary hypertension.
What will cause the blockage of the blood to the brain?
A stroke or brain aneurysm can result in sudden blockage of blood flow the brain, which can result in disability or death. Other conditions, such as central nervous system vasculitis can also cause similar symptoms.
Is the blood deoxegenated or oxygenated in the pulmonary circuit?
Blood entering the pulmonary circuit is deoxygenated. Blood leaving the pulmonary circuit is oxygenated.
What is different about pulmonary arteries and pulmonary veins?
The pulmonary artery and pulmonary vein originates in the heart. What is different about them is that the pulmonary artery carries deoxygenated blood (blood without oxygen) as supposed to other arteries, which carry oxygenated blood. And the pulmonary vein carries oxygenated blood unlike other veins, which carry deoxygenated blood.
What is the operation to replace blocked coronary vessels?
it is called a bypass. doctors take a piece of artery (often from the leg) and attach it on either side of the blockage so that that the blood can go around the obstruction.
