Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure.
Cardiogenic pulmonary edema. Pulmonary edema that is due to a direct problem with the heart is called cardiogenic. Congestive heart failure is a common cause of cardiogenic pulmonary edema; in this condition, the left ventricle cannot pump out enough blood to meet the needs of the body. This causes a buildup of pressure in other parts of the circulatory system, forcing fluid into the air sacs of the lungs and other parts of the body.
1. edema caused by the accumulation of fluid in the extracellular spaces of a tissue. 2. pulmonary edema in the interstitial tissues; there is dyspnea but no hypoxemia. edema neonatoÂ´rum sclerema neonatorum. nonpitting edema edema in which pressure does not leave a depression in the tissues, such as in cellular edema.itting edema edema in which external pressure leaves a persistent depression in the tissues (see pitting); it occurs because the pressure pushes the excess fluid out of the intercellular spaces in the tissue. See also nonpitting edema.
