As the pulmonary venous pressure rises, these pressures overwhelm the barriers and fluid enters the alveoli when the pressure is above 25 mmHg. [14] Depending on whether the cause is acute or chronic determines how fast pulmonary edema develops and the severity of symptoms. [12] Some of the common causes of cardiogenic pulmonary edema include:
Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [1]
