NPPE develops as a result of significant negative pressure generated in the chest cavity by inspiration against an upper airway obstruction. These negative pressures in the chest lead to increase venous supply to the right side of the heart while simultaneously creating more resistance for the left side of the heart to supply blood to the rest of the body ().

The initial management of pulmonary edema, irrespective of the type or cause, is supporting vital functions while edema lasts. Hypoxia may require supplementary oxygen to balance blood oxygen levels, but if this is insufficient then again mechanical ventilation may be required to prevent complications caused by hypoxia.

High-altitude pulmonary edema (HAPE) is a life-threatening form of non-cardiogenic pulmonary edema that occurs in otherwise healthy people at altitudes typically above 2,500 meters (8,200 ft). [2] HAPE is a severe presentation of altitude sickness. Cases have also been reported between 1,500–2,500 metres or 4,900–8,200 feet in people who ...
Swimming induced pulmonary edema (SIPE), also known as immersion pulmonary edema, is a life threatening condition that occurs when fluids from the blood leak abnormally from the small vessels of the lung (pulmonary capillaries) into the airspaces (alveoli).

The supportive therapies focus on maximizing pulmonary function and preserving activity tolerance through oxygen therapy, bronchodilators, inhaled beta-adrenergic agonists, and diuretics. [10] Because there is no effective treatment for restrictive lung disease, prevention is key. [10]
There is ongoing interest into establishing connections of cardiac asthma to abnormalities in bronchiole anatomy. [1] [4] Current evaluation has proposed multiple mechanisms for increased airway resistance, and focus is on four alternate explanations: Bronchoconstriction as a result of pulmonary edema. [2] [4]
The 17th edition of the textbook is dedicated to George W. Thorn, who was editor of the first seven editions of the book and editor in chief of the eighth edition. He died in 2004. The 18th edition of the book (ISBN 978-0071748896) was edited by Anthony Fauci, Dennis Kasper, Stephen Hauser, J. Larry Jameson and Joseph Loscalzo. New chapters ...
