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 .
Also increased pneumonia risk exists in patients with esophageal dysphagia when compared to stroke patients because patients with stroke will improve as they recover from their acute injury, whereas esophageal dysphagia is likely to worsen with time. In one cohort of aspiration pneumonia patients, overall three-year mortality was 40%. [16]
One cause of obstruction, especially in young children, is inhalation of a foreign object such as a marble or toy. The object lodges in a small airway, and pneumonia develops in the obstructed area of the lung. Another cause of obstruction is lung cancer, which can block the flow of air. Lung disease - Patients with underlying lung disease are ...
Aspiration can result in patient death through a variety of mechanisms. It is important to recognize and diagnose early in order to improve patient outcomes. Death from aspiration and aspiration-related syndromes is most common in elderly patients with known baseline risk factors, though it frequently goes unrecognized. [18]
Edema (American English), also spelled oedema (British English), and also known as fluid retention, dropsy and hydropsy, is the build-up of fluid in the body's tissue, [1] a type of swelling. [4] Most commonly, the legs or arms are affected. [ 1 ]
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 ...
In the lungs, the extra fluid accumulates into the air sacs within the lung, causing difficulties in oxygen getting into the blood. This results in low blood oxygen levels and shortness of breath. In the arms and legs, the fluid accumulates in the tissues, causing swelling. This is most prominent in the legs due to the effects of gravity.
Other causes of pulmonary edema that require rapid intervention and should be considered first include fluid overload, brain injury, and anaphylaxis. If when considering these differentials, there is no evidence for administration of excessive fluids, no focal signs suggesting a brain injury, and so signs of allergic reaction, one can then ...
