Acute lung injury may cause pulmonary edema directly through injury to the vasculature and parenchyma of the lung, causes include: Inhalation of hot or toxic gases [12] (including vaping-associated lung injury) Pulmonary contusion, i.e., high-energy trauma (e.g. vehicle accidents) Aspiration, e.g., gastric fluid
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 ...
It causes drowsiness or loss of consciousness, leading to brain herniation and death. Pulmonary edema occurs when the pressure in blood vessels in the lung is raised because of obstruction to the removal of blood via the pulmonary veins. This is usually due to failure of the left ventricle of the heart.
ARDS is a form of fluid accumulation in the lungs not explained by heart failure (noncardiogenic pulmonary edema). It is typically provoked by an acute injury to the lungs that results in flooding of the lungs' microscopic air sacs responsible for the exchange of gases such as oxygen and carbon dioxide with capillaries in the lungs.

Immersion causes increased external hydrostatic pressure, leading to redistribution of blood from the periphery to the chest, which increases cardiac filling pressures and stroke volume, and also reduces total lung capacity. There is a movement of fluid from the alveolar capillaries into the alveoli and extravascular lung tissues, which ...
In humans, the left and right lungs are completely separated by the mediastinum, and there is no communication between their pleural cavities.Therefore, in cases of a unilateral pneumothorax, the contralateral lung will remain functioning normally unless there is a tension pneumothorax, which may shift the mediastinum and the trachea, kink the great vessels, and eventually collapse the ...
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.
Hydrothorax is the synonym of pleural effusion in which fluid accumulates in the pleural cavity.This condition is most likely to develop secondary to congestive heart failure, following an increase in hydrostatic pressure within the lungs.
