A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
Pleural empyema is a collection of pus in the pleural cavity caused by microorganisms, usually bacteria. [1] Often it happens in the context of a pneumonia, injury, or chest surgery. [1] It is one of the various kinds of pleural effusion.
Sometimes the fluid contains thick pus or blood clots, or it may have formed a hard skin or peel. This makes it harder to drain the fluid. To help break up the pus or blood clots, the doctor may use the chest tube to put certain medicines into the pleural space. These medicines are called fibrinolytics. If the pus or blood clots still do not ...
About 2–3% of all fluid collections surrounding the lungs (pleural effusions) are chylothoraces. [2] It is important to distinguish a chylothorax from a pseudochylothorax (a pleural effusion that happens to be high in cholesterol ), which has a similar appearance visually but is caused by more chronic inflammatory processes and requires a ...
This is called the pleural cavity (also pleural space). [2] It contains a tiny amount of serous fluid (pleural fluid) secreted by the pleurae, at an average pressure that is below the atmospheric pressure under healthy conditions. The two lungs, each bounded by a two-layered pleural sac, almost fill the thoracic cavity.
A subpulmonic effusion is excess fluid that collects at the base of the lung, in the space between the pleura and diaphragm. It is a type of pleural effusion in which the fluid collects in this particular space but can be "layered out" with decubitus chest radiographs.
A pleural effusion is an accumulation of fluid inside the pleural space. If this collection of fluid gets large enough, it can also push structures in the chest away from it and cause a mediastinal shift. However, a pleural effusion can also pull the mediastinal structure towards itself.
Pulmonary aspiration is the entry of solid or liquid material such as pharyngeal secretions, food, drink, or stomach contents from the oropharynx or gastrointestinal tract, into the trachea and lungs. [1] When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as "going down the ...
