Flash pulmonary edema is a clinical syndrome that begins suddenly and accelerates rapidly. Essentially all patients will present to the emergency department by ambulance. The initiating acute event often a vascular event such as intense vasoconstriction and not a cardiac event such as myocardial infarction.
Acute interstitial pneumonitis occurs most frequently among people older than forty years old. It affects men and women equally. There are no known risk factors; in particular, smoking is not associated with increased risk. [citation needed]
Intravascular fluid overload leads to polyuria and can cause flash pulmonary edema and cardiac arrest, with possibly fatal consequences. [4] [5] Death from SCLS typically occurs during this recruitment phase because of pulmonary edema arising from excessive intravenous fluid administration during the earlier leak phase.
Flash Pulmonary Edema or Crash Pulmonary Edema is a clinical characterization of acute heart failure with a dramatic presentation. [4] It is an acute cardiac disease precipitated by cardiac events and usually associated with severe hypertension.
The cause of TRALI is currently not fully understood. 80–85% of cases are thought to be immune mediated. [5] [6] Antibodies directed toward human leukocyte antigens (HLA) or human neutrophil antigens (HNA) have been implicated, with transfused antibodies shown to bind antigens expressed on pulmonary endothelial cells to initiate acute inflammation in the lungs.
People who are predisposed to develop high-altitude pulmonary edema may present a reduction in urine production before respiratory symptoms become apparent. [ 15 ] Humans have survived for two years at 5,950 m (19,520 ft, 475 millibars of atmospheric pressure), which is the highest recorded permanently tolerable altitude; the highest permanent ...
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 ().

Lower airway: may occur from bronchospasm, drowning, or airspace filling disorders (e.g. pneumonia, pulmonary edema, pulmonary hemorrhage). [7] Obstructive conditions of the lower airway, including severe asthma or COPD episodes, can also lead to respiratory arrest. During these episodes, known as exacerbations, airway resistance is increased ...
