The term pulmonary edema literally means wet lungs. This term actually refers to a pathological condition of the lungs, frequently demonstrated by chest X-ray. Edema of the lungs should be thought of as the result of a disease such as congestive heart failure and not a disease in and of itself. In this case it would be a cardiac disease and not ...
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 ().

In 1994, a new definition was recommended by the American-European Consensus Conference Committee [6] [10] which recognized the variability in severity of pulmonary injury. [51] The definition required the following criteria to be met: acute onset, persistent dyspnea; bilateral infiltrates on chest radiograph consistent with pulmonary edema
Restrictive lung diseases are a category of extrapulmonary, pleural, or parenchymal respiratory diseases that restrict lung expansion, [2] resulting in a decreased lung volume, an increased work of breathing, and inadequate ventilation and/or oxygenation. Pulmonary function test demonstrates a decrease in the forced vital capacity.
The invading organism starts multiplying, thereby releasing toxins that cause inflammation and edema of the lung parenchyma. This leads to the accumulation of cellular debris within the lungs. This leads to consolidation or solidification, terms used for macroscopic or radiologic appearance of the lungs affected by pneumonia.
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), [3] is a group of respiratory diseases affecting the interstitium (the tissue) and space around the alveoli (air sacs) of the lungs. [4] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It ...
Crackles can be heard in people who have pneumonia, atelectasis, pulmonary fibrosis, acute bronchitis, bronchiectasis, acute respiratory distress syndrome (ARDS), interstitial lung disease or post thoracotomy or metastasis ablation. Pulmonary edema secondary to left-sided congestive heart failure and high altitude pulmonary edema can also cause ...
