As such, cyanide poisoning is a form of histotoxic hypoxia, because it interferes with the ability of cells to take or use oxygen via oxidative phosphorylation. [ 25]: 1475. Specifically, cyanide binds to the heme a3-CuB binuclear center ...

Trepopnea. Trepopnea /tɹɛpəʊpˈniːə/ is dyspnea (shortness of breath) that is sensed while lying on one side but not on the other [ 1] (lateral recumbent position). It results from disease of one lung, one major bronchus, or chronic congestive heart failure that affects only a side of breathing. Patients with trepopnea in most lung ...
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). [ 2][ 3] SIPE usually occurs during exertion in conditions of water immersion, such as ...
