Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange , most often leading to shortness of breath ( dyspnea ) which can progress to hypoxemia and respiratory failure .
This results in an increased amount of fluid shifting from these vessels into the lower pressure extravascular space. While there normally is a net passage of fluid out of the vasculature at baseline, this is a small enough amount to be drained from the extravascular space by the lymphatic system, and as such fluid does not accumulate. In the ...
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 ...

Excess fluid from the pleural space is drained into a bag. Instruments for thoracocentesis and needle biopsy of the pleura [8] This procedure is indicated when unexplained fluid accumulates in the chest cavity outside the lung. In more than 90% of cases analysis of pleural fluid yields clinically useful information.
Excess fluid from the pleural space is drained into a bag. Once the presence of an excess fluid in the pleural cavity, or pleural effusion, is suspected and location of fluid is confirmed, a sample of fluid can be removed for testing. [14] The procedure to remove fluid in the chest is called a diagnostic thoracentesis. [15]
Studies show that keeping your head at the appropriate height—about 2 inches (or 5 centimeters) off the bed—helps air flow into the lungs and stabilizes your respiratory function. However ...
