The pathophysiology of acute respiratory distress syndrome involves fluid accumulation in the lungs not explained by heart failure (noncardiogenic pulmonary edema). It is typically provoked by an acute injury to the lungs that results in flooding of the lungs' microscopic air sacs responsible for the exchange of gases such as oxygen and carbon dioxide with capillaries in the lungs.

[1] Constipation or diarrhea, emesis, anorexia, early satiety, and abdominal pain are common symptoms of gastrointestinal dysmotility, which affects 70% of patients. [1] Although about a quarter of patients report neuropathic symptoms such as tingling in the distal extremities, sensory examination and nerve conduction studies are normal. [1]
The origins of pathophysiology as a distinct field date back to the late 18th century. The first known lectures on the subject were delivered by Professor August Friedrich Hecker at the University of Erfurt in 1790, and in 1791, he published the first textbook on pathophysiology, Grundriss der Physiologia pathologica, [2] spanning 770 pages.

Cushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia.

A summary of the pathophysiology of a type 1 hypersensitivity reaction. Type I hypersensitivity can be further classified into immediate and late-phase reactions. Within minutes of exposure to an antigen, the immediate hypersensitivity occurs, releasing histamines and lipid mediators which are responsible for the initial allergic reaction response.
Asthma is a common pulmonary condition defined by chronic inflammation of respiratory tubes, tightening of respiratory smooth muscle, and episodes of bronchoconstriction. [1] The Centers for Disease Control and Prevention estimate that 1 in 11 children and 1 in 12 adults have asthma in the United States of America. [ 1 ]
Unlike HUS and aHUS, [39] [40] TTP is known to be caused by a defect in the ADAMTS13 protein, [41] so a lab test showing ≤5% of normal ADAMTS13 levels is indicative of TTP. [28] ADAMTS13 levels above 5%, coupled with a positive test for shiga-toxin / enterohemorrhagic E. coli (EHEC), are more likely indicative of HUS, [ 42 ] whereas absence ...
Synonyms for PCP include pneumocystosis [1] (pneumocystis + -osis), pneumocystiasis [1] (pneumocystis + -iasis), and interstitial plasma cell pneumonia. [1] The older species name Pneumocystis carinii (which now applies only to the Pneumocystis species that is found in rats [28]) is still in common usage.
