Examples of edema in the following topics:
-
- Causes of edema which are generalized to the whole body can cause edema in multiple organs and peripherally.
- For example, severe heart failure can cause pulmonary edema, pleural effusions, ascites, and peripheral edema.
- Causes of edema which are generalized to the whole body can cause edema in multiple organs and peripherally.
- For example, severe heart failure can cause pulmonary edema, pleural effusions, ascites, and peripheral edema.
- Examples of edema in specific organs include cerebral edema, pulmonary edema, periorbital edema (eye puffiness), and cutaneous edema due to mosquito bites, spider bites, bee stings, or contact dermatitis).
-
- Pulmonary edema is fluid accumulation in the air spaces and parenchyma of the lungs.
- It is due to either failure of the left ventricle of the heart to adequately remove blood from the pulmonary circulation ("cardiogenic pulmonary edema") or an injury to the lung parenchyma or vasculature of the lung ("noncardiogenic pulmonary edema").
- Pulmonary edema, especially in the acute setting, can lead to respiratory failure, cardiac arrest due to hypoxia, and death.
- There is no one single test for confirming that breathlessness is caused by pulmonary edema.
- Interstitial and alveolar pulmonary edema with small pleural effusions on both sides.
-
- It is characterized by proteinuria (>3.5g/day), hypoalbuminemia, hyperlipidemia, and edema (which is generalized and also known as anasarca or dropsy).
- The edema begins in the face .
- Peripheral pitting edema results from water retention.
-
- A physiological shunt can develop if there is infection or edema in the lung that obstructs an area.
- A physiological shunt can develop if there is infection or edema in the lung which decreases ventilation, but does not affect perfusion; thus, the ventilation/perfusion ratio is affected.
- Pulmonary edema with small pleural effusions on both sides (as shown) can cause changes in the V/Q ratio.
-
- Fluid removal from tissues prevents the development of edema.
- Edema is any type of tissue swelling from increased flow of interstitial fluid into tissues relative to fluid drainage.
- While edema is a normal component of the inflammation process, in some cases it can be very harmful.
- Cerebral and pulmonary edema are especially problematic, which is why lymph drainage is so important.
- Abnormal edema can still occur if the drainage components of the lymph vessels are obstructed.
-
- As healing starts, fibrosis may occur in the inflamed areas and cause obstruction of the lymphatic system and edema.
- The fibrosis and edema are considered the third stage of LGV and are mainly permanent.
-
- Sometimes the removal of tissue fluid does not function correctly, and there is a build-up, which is called edema.
- Edema is responsible for the swelling that occurs during inflammation, and in certain diseases in which lymphatic drainage pathways are obstructed.
-
- Rales or crackles, heard initially in the lung bases and later throughout the lung fields suggest the development of pulmonary edema (fluid in the alveoli).
- Cyanosis, which suggests severe hypoxemia, is a late sign of extremely severe pulmonary edema.
-
- Obstructive diseases and conditions include emphysema, asthma, and pulmonary edema.
- The obstruction may be due to edema, smooth muscle spasms in the walls of the bronchioles, increased mucus secretion, damage to the epithelia of the airways, or a combination of these events.
- Those with asthma or edema experience increased occlusion from increased inflammation of the airways.
-
- Under normal conditions, lymph capillaries prevent the accumulation of edema (abnormal swelling) in the tissues.
- However, edema will still occur during acute inflammation or diseases in which lymph vessels are obstructed.
