A pleural effusion is a build up of fluid between the (visceral and parietal) layers which line the lungs and chest cavity.
Whereas.......
A pulmonary embolus is a sudden blockage in a lung artery caused by a blood clot that travels to the lung from another part of the body.
NB:
- Pleural effusion = problem in visceral and parietal layers
- Pulmonary embolus = problem in lung artery
DefinitionParapneumonic pulmonary effusion is an build up of fluid between layers of the tissue lining the lung and the chest cavity, which develops in the setting of pneumonia.
no
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.
They are essentially the same.
nothing
In moderate pulmonary embolism, the predicted oxygen saturation may vary depending on the individual, but it is typically lower than normal levels. Patients may present with oxygen saturation levels below 90%, indicating impaired oxygen exchange in the lungs due to the blockage of blood flow to the lungs. Monitoring oxygen saturation is important in assessing the severity of pulmonary embolism and guiding treatment.
Effusion and diffusion are both processes by which particles move from an area of high concentration to an area of low concentration. The key difference is that effusion specifically refers to the movement of gas particles through a small opening, while diffusion is the overall movement of particles in a substance.
Coronary or cardio is blood flow. Pulmonary or respiratory is breathing.
No evidence of pleural effusion means that there is no fluid accumulation in the space between the layers of the pleura (lining around the lungs). This can be determined through imaging studies like chest X-rays or ultrasound, which show if there is any excess fluid present in the pleural space.
An abdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta, often due to a weakening of the vessel wall, which can lead to rupture and serious internal bleeding. In contrast, a pulmonary embolism (PE) occurs when a blood clot travels to the lungs, blocking a pulmonary artery and potentially causing respiratory distress or collapse. While AAA primarily affects the aorta and is related to vascular integrity, PE involves the lungs and is typically associated with venous thromboembolism. Both conditions are life-threatening but arise from different underlying mechanisms and require distinct management strategies.
