Hypoxia and Medicine

what is the difference between Hypoxia and Ischemia?

Public Comments

1. Very VERY basically, hypoxia is deficient oxygen to body tissue, and ischemia is deficient blood supply.
2. Hypoxia is a pathological condition in which the body as a whole (generalized hypoxia) or a region of the body (tissue hypoxia) is deprived of adequate oxygen supply. Variations in arterial oxygen concentrations can be part of the normal physiology, for example, during strenuous physical exercise. A mismatch between oxygen supply and its demand at the cellular level may result in a hypoxic condition In medicine, ischemia (Greek ισχαιμία, isch- restriction, hema or haema blood) is a restriction in blood supply, generally due to factors in the blood vessels, with resultant damage or dysfunction of tissue. It may also be spelled ischaemia or ischæmia. It also means local anemia in a given part of a body sometimes resulting from vasoconstriction, thrombosis or embolism.
