Stasis is a term used to describe the state in which blood flow is stopped. It is a medical condition in which the flow of blood within a vessel or organ is reduced or completely halted. This can be caused by a variety of factors, including trauma, infection, and blockage of the vessel. STASIS can lead to serious complications, such as tissue death, infection, and even organ failure. Treatment for STASIS depends on the underlying cause, but may include medications, surgery, or lifestyle changes.
