Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
A chokehold, choke, stranglehold or, in Judo, shime-waza (Japanese: 絞技, lit. 'constriction technique') [1] is a general term for a grappling hold that critically reduces or prevents either air [2] or blood from passing through the neck of an opponent. The restriction may be of one or both and depends on the hold used and the reaction of the ...
A choke-out is a hand-to-hand combat tactic involving the use of a chokehold to cause syncope, or temporary loss of consciousness, at which point the choke is released.. Common chokeholds in grappling used to accomplish a choke-out include the rear naked choke, arm triangle, triangle choke, and the guil
Anemia and carbon monoxide poisoning are common causes of hypemic hypoxia. Ischemic hypoxia ( or "stagnant hypoxia") – Reduced brain oxygen is caused by inadequate blood flow to the brain. Stroke, shock, cardiac arrest and heart attack may cause stagnant hypoxia. Ischemic hypoxia can also be created by pressure on the brain.
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Ischemia is a vascular disease involving an interruption in the arterial blood supply to a tissue, organ, or extremity that, if untreated, can lead to tissue death. It can be caused by embolism, thrombosis of an atherosclerotic artery, or trauma. Venous problems like venous outflow obstruction and low-flow states can cause acute arterial ischemia.
Researchers also tested the response of mice to experiencing cerebral ischemia, a cutting off of blood flow to the brain, and myocardial ischemia, a cutting off of blood flow to the heart, both ...
Repeated bouts of ischemia and reperfusion injury also are thought to be a factor leading to the formation and failure to heal of chronic wounds such as pressure sores and diabetic foot ulcer. [4] Continuous pressure limits blood supply and causes ischemia, and the inflammation occurs during reperfusion.
