- Effusion is the process in which a gas escapes through a small hole. This occurs if the diameter of the hole is considerably smaller than the mean free path of the molecules. According to Graham's law, the rate at which gases effuse (i.e., how many molecules pass through the hole per second) is dependent on their molecular weight.

What causes pleural effusion? What causes pleural effusion? Dr. Nader describes pleural effusion as fluid that forms around the lung, between the lung and chest wall. He says it usually occurs as a result of active lung cancer. The fluid is typically removed and analyzed to determine its cause. Learn about interventional pulmonology for lung cancer.

What is an Ankle Effusion? Ankle effusion is a buildup of fluid in the ankle joint. Effusion causes pain and swelling in the ankle, and it can lead to complications because it may put pressure on tissues in the surrounding area and damage them. Treatment of ankle effusion depends on the severity of the effusion and the cause.rauma to the ankle may result in effusion. Anti-inflammatory drugs may be prescribed to help treat an ankle effusion. Ice might be recommended to treat the swelling of an ankle effusion. A proper diagnosis by a medical doctor is often needed to treat ankle pain, such as that from ankle effusion.

Diffusion and Effusion Effusion refers to the movement of gas particles through a small hole. Graham's Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles. diffusion movement of particles from an area of high concentration to one of low concentration.

Pericardial Effusion The term pericardial effusion describes a collection of fluid in the pericardial space. The amount of fluid may range in volume from a few millilitres up to 2 litres. It may be a transudate (hydropericardium), exudate (pyopericardium) or haemopericardium.

Disorders of the Pleural Cavity Pleural effusion - A pleural effusion refers to a build-up of fluid in the pleural cavity. When too much fluid accumulates in this space it can interfere with the expansion of the lungs with inspiration. There are many causes, with the most common being viral infections and congestive heart failure.

- Exudative: The pleural effusion fluid has excess protein, blood, or evidence of inflammation or infection. An exudative pleural effusion may require drainage, depending on its size and the severity of inflammation. Causes of exudative pleural effusion include pneumonia and lung cancer. The type of pleural effusion can only be identified by taking a sample of fluid from the pleural effusion.

What Is a Pleural Effusion? A pleural effusion is an abnormal amount of fluid around the lung. Pleural effusions can result from many medical conditions. Most pleural effusions are not serious by themselves, but some require treatment to avoid problems.ymptoms are more likely when a pleural effusion is moderate or large-sized, or if inflammation is present. Symptoms of pleural effusions may include: 1  Shortness of breath. 2  Chest pain, especially on breathing in deeply (pleurisy, or pleuritic pain).

Overview By Mayo Clinic Staff. Print. Pericardial effusion (per-e-KAHR-dee-ul uh-FU-zhun) is the accumulation of too much fluid in the double-layered, sac-like structure around the heart (pericardium). The space between the layers normally contains a thin layer of fluid. But if the pericardium is diseased or injured, the resulting inflammation can lead to excess fluid. Fluid can also build up around the heart without inflammation, such as from bleeding after a chest trauma. Pericardial effusion puts pressure on the heart, affecting the heart's function.

Effusion Definition, Types, Causes, Symptoms, Treatment Effusion Definition. Effusion is the term for accumulation of fluid in a body cavity particularly within the cranial cavity, in the middle ear, around the lungs, around the heart, in the abdomen (peritoneal cavity) and in the joint spaces. It is also referred to as fluid retention or water retention because most of the fluid is composed of water.
