The development of pulmonary edema may be associated with symptoms and signs of "fluid overload" in the lungs; this is a non-specific term to describe the manifestations of right ventricular failure on the rest of the body.
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.
Hypervolemia, also known as fluid overload, is the medical condition where there is too much fluid in the blood. The opposite condition is hypovolemia, which is too little fluid volume in the blood. Fluid volume excess in the intravascular compartment occurs due to an increase in total body sodium content and a consequent increase in ...
The person may, in fact, have too little fluid in their blood vessels, but if the low blood pressure is due to cardiogenic shock, the administration of additional fluid may worsen the heart failure and associated low blood pressure. If the person's circulatory volume is adequate but there is persistent evidence of inadequate end-organ perfusion ...
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 ...
Transfusion-related acute lung injury (TRALI) is the serious complication of transfusion of blood products that is characterized by the rapid onset of excess fluid in the lungs. [1] It can cause dangerous drops in the supply of oxygen to body tissues.
An imbalance can cause fluid overload in the spaces between cells or tissues, which can lead to edema, per the National Institutes of Health. Edema refers to the swelling that happens when the ...
This can be done with electrocardiogram, echocardiogram, measurement of cardiac enzymes, etc. 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 ...
