Edema may be described as pitting edema, or non-pitting edema. [32] Pitting edema is when, after pressure is applied to a small area, the indentation persists after the release of the pressure. Peripheral pitting edema, as shown in the illustration, is the more common type, resulting from water retention.
Inadequate intake of free water associated with total body sodium depletion. Typically in elderly or otherwise disabled patients who are unable to take in water as their thirst dictates and also are sodium depleted. This is the most common cause of hypernatremia. [citation needed]
The symptoms of TACO can include shortness of breath , low blood oxygen levels , leg swelling (peripheral edema), high blood pressure (hypertension), and a high heart rate (tachycardia). [ 3 ] It can occur due to a rapid transfusion of a large volume of blood but can also occur during a single red blood cell transfusion (about 15% of cases). [ 2 ]
These include parts of the body affected by gravity, such as the extremities, but edema can occur in any area. Symptoms of water retention include: Swelling in legs, arms, feet or hands. Distended ...
Heat edema is a cutaneous condition characterized by dependent edema from vasodilatory pooling. [2] Heat causes the blood vessels to expand (dilate), so body fluid moves into the hands or legs by gravity. The balance of salt in the body is also a risk factor for heat edema.
Peripheral edema is edema (accumulation of fluid causing swelling) in tissues perfused by the peripheral vascular system, usually in the lower limbs. In the most dependent parts of the body (those hanging distally ), it may be called dependent edema.
