clotting time clotting time (coagulation time) the time required for blood to clot in a glass tube; see also clotting. cold ischemia time the time between the placement of a traumatically amputated body part in ice and the time of surgical replantation. inertia time the time required to overcome the inertia of a muscle after reception of a stimulus. ischemia time the total time between traumatic amputation of a limb or portion of a limb and its surgical reimplantation; it is the sum of warm and cold ischemia times. minimal response time in radiology, the shortest possible exposure time for an x-ray film to be exposed automatically.

what is lateral wall ischemia Ischemia means the perfusion of the blood is blocked or decreased usually due to plaque buildup within the vessel. The cath will be fed through a vessel to the area of ischemia and assess the degree of blockage and exact location. Usually, there is a stent implant to open the vessel to better blood flow. Hope this helps, and if you have any further questions or comments you are welcome to respond.

Century - Myocardial Ischemia VS infarction development of arterial branching that occurs within the coronary circulation when occlusion of the coronary arteries occurs slowly over a long period. Myocardial ischemia. Results when supply of blood to the myocardiam from the coronary arteries is insufficient to meet myocardial oxygen demands. what is the difference between ischemia and angina. ischemia is what is happening in the heart and angina is the symptom/pain experienced with low blood flow.

Brain ischemia Brain ischemia (aka cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. This leads to poor oxygen supply or cerebral hypoxia and thus to the death of brain tissue or cerebral infarction / ischemic stroke.

Molecular and Cellular Mechanisms of Ischemia-Induced Neuronal Death Focal ischemia or cerebral infarction is the condition or state in which a specific area of brain tissue undergoes injury as a consequence of a temporary or permanent obstruction of local blood supply. Focal ischemia results in death of both neurons and nonneuronal cells in contiguous areas of brain, usually representing a single vascular territory.

Amputation Traumatic/replantation History. 1  Exact time of injury is critical, as ischemia time predicts success for replantation: Irreversible muscle necrosis begins at 6 hr of ischemia. The temperature and amount of muscle present in the tissue predicts the tolerable ischemia time.

Ischemia Curve B - a set of short ischemic episodes (ischemic preconditioning) before prolonged ischemia provides functional recovery of contractile activity of the heart at reperfusion. Ischemia results in tissue damage in a process known as ischemic cascade. The damage is the result of the build-up of metabolic waste products, inability to maintain cell membranes, mitochondrial damage, and eventual leakage of autolyzing proteolytic enzymes into the cell and surrounding tissues.

What is Frostbite? The most common cold weather illnesses are frostbite and hypothermia. Frostbite Frostbite is an injury to the body that is caused by freezing. Frostbite causes a loss of feeling and color in affected areas. It most often affects the nose, ears, cheeks, chin, fingers, or toes.

Brain ischemia Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis. There are two types of ischemia: focal ischemia, which is confined to a specific region of the brain; and global ischemia, which encompasses wide areas of brain tissue.The main symptoms involve impairments in vision, body movement, and speaking.ther effects that may result from brain ischemia are stroke, cardiorespiratory arrest, and irreversible brain damage. An interruption of blood flow to the brain for more than 10 seconds causes unconsciousness, and an interruption in flow for more than a few minutes generally results in irreversible brain damage.

Ischemia - Topic Overview What is ischemia? Ischemia is the medical term for what happens when your heart muscle doesn't get enough oxygen. Ischemia usually happens because of a shortage of blood and oxygen to the heart muscle. It is usually due to narrowing or blockage of one or more of the coronary arteries (which supply blood to the heart muscle). In many cases ischemia is a temporary problem. Your heart may be ...

Cold agglutinin disease Cold agglutinin disease is an autoimmune disease characterized by the presence of high concentrations of circulating antibodies, usually IgM, directed against red blood cells. It is a form of autoimmune hemolytic anemia, specifically one in which antibodies only bind red blood cells at low body temperatures, typically 28–31 °C. Cold agglutinin disease was first described in 1957.

ischemia Ischemia is an insufficient supply of blood to an organ, usually due to a blocked artery. Myocardial ischemia is an intermediate condition in coronary artery disease during which the heart tissue is slowly or suddenly starved of oxygen and other nutrients. Eventually, the affected heart tissue will die. When blood flow is completely blocked to the heart, ischemia can lead to a heart attack.

Ischemia 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 atherosclerosis artery, or trauma.

- Hypothermia is a physical condition that occurs when the body's core temperature falls below a normal 98.6° F (37° C) to 95° F (35° C) or cooler. Think of hypothermia as the opposite of heat stroke.Cold water dangerously accelerates the onset and progression of hypothermia since body heat can be lost 25 times faster in cold water than in cold air. Hypothermia affects the body's core the brain, heart, lungs, and other vital organs.hink of hypothermia as the opposite of heat stroke.

Ischemia Brain ischemia is insufficient blood flow to the brain, and can be acute or chronic. Acute ischemic stroke is a neurologic emergency that may be reversible if treated rapidly. Chronic ischemia of the brain may result in a form of dementia called vascular dementia.

- Ischemia is a symptom in which a person does not have enough blood supply to a part of the body, making that part of the body ischemic. For example, in a heart attack, a coronary artery is blocked so blood cannot get to the heart muscle beyond the blockage point. The heart muscle lacking blood supply has ischemia.

- Ischemia is any reduction in blood flow resulting in decreased oxygen and nutrient supplies to a tissue. Ischemia may be reversible, in which case the affected tissue will recover if blood flow is restored, or it may be irreversible, resulting in tissue death.schemia is any reduction in blood flow resulting in decreased oxygen and nutrient supplies to a tissue. Ischemia may be reversible, in which case the affected tissue will recover if blood flow is restored, or it may be irreversible, resulting in tissue death.

Rigor mortis Cold shortening is caused by the release of stored calcium ions from the sarcoplasmic reticulum of muscle fibers in response to the cold stimulus. The calcium ions trigger powerful muscle contraction aided by ATP molecules.

- Acute limb ischemia is defined as a sudden decrease in limb perfusion leading to failure to meet the oxygen and nutrient requirements of limb tissue, resulting in tissue ischemia. Ischemic tissue is characterized by hypoxia (decreased oxygen levels) and the accumulation of metabolic wastes such as lactic acid.
