Hemorrhaging
|
|
HemorrhagingHeavy bleeding. A cerebral hemorrhage can lead to a stroke.
RELATED TERMS--------------------------------------
Cerebral
Referring to the cerebrum.
Hemorrhage
A general term for loss of blood, often profuse, brought about by injury to the blood vessels or by a deficiency of certain necessary blood elements such as platelets.
Stroke
A stroke, or a Cerebrovascular Accident, occurs when blood vessels that deliver oxygen to the brain, either rupture or become clogged, causing brain/nerve cells to die. Results are usually devastating as nerve/brain cells are not replaced. Usually characterized by a slurring of words, weakness on one side of the body, and a drooping facial expression on one side of the face.
SIMILAR TERMS--------------------------------------
Hemochromatosis
A disorder due to the deposition of hemosiderin in the parenchymal cells, causing tissue damage and dysfunction of the liver, pancreas, heart, and pituitary. Full development of the disease in women is restricted by menstruation, pregnancy, and lower dietary intake of iron. Acquired hemochromatosis may be the result of blood transfusions, excessive dietary iron, or secondary to other disease. Idiopathic or genetic hemochromatosis is an autosomal recessive disorder of metabolism associated with a gene tightly linked to the A locus of the HLA complex on chromosome 6.
Hemodialysis
A mechanical method of cleaning the blood for people who have kidney disease. See also: Dialysis.
Hemodynamic
Relating to the physical aspects of the blood circulation.
Hemoglobin
Hemoglobin is a substance contained within the red blood cells and is responsible for their color. It has the unique property of combining reversibly with oxygen and is the medium by which oxygen is transported within the body. It takes up oxygen as blood passes through the lungs and releases it as blood passes through the tissues.
Hemolysis
The destruction of red blood cells.
Hemolytic disease of the newborn
Also called Rh disease or erythroblastosis, hemolytic disease results when a woman who is Rh-negative (meaning she does not carry the Rh protein in her blood) has a fetus who is Rh-positive and her immune system makes antibodies against the fetus's blood. The disorder is treated with a compound that prevents the woman's immune system from making antibodies.
Hemolytic Uremic Syndrome
Hemolytic anemia and thrombocytopenia occurring with acute renal failure.
Hemophilia
A genetic blood disorder, almost always in males, in which blood does not clot properly as a result of an enzyme deficiency.
Hemopoietic
Pertaining to or related to the formation of blood cells.
Hemoptysis
A cough that produces blood.
Hemorrhage
A general term for loss of blood, often profuse, brought about by injury to the blood vessels or by a deficiency of certain necessary blood elements such as platelets.
Hemorrhoid
Caused by increased blood volume and pressure from the uterus on the veinsin the legs and pelvis, these swollen blood vessels in the anus are commonduring pregnancy. Constipation can also cause (or compound) the problem.
Hemorrhoidectomy
An operation to remove hemorrhoids.
Hemorrhoids
Enlarged veins protruding into the anorectal area, either internal or externally visible. They are either the result of poor sphincter tone and portal congestion, or sphincter hypertonicity, skeletal muscle and adrenergic excess.
Hemostasis
Arrest of blood circulation.
PREVIOUS AND NEXT TERMS--------------------------------------
Heart Failure (congestive heart failure, CHF)
A chronic, progressive disease in which the myocardium (heart muscle) weakens and can not pump blood efficiently. Fluid accumulates in the lungs, hands, ankles, or other parts of the body.
Heart Lung Bypass Machine
A machine that oxygenates the blood and circulates it throughout the body during surgery.
Heart Monitor
An electrocardiography machine designed to monitor heart function continuously.
Heart Surgery
Heart surgery is any surgery, which involves the heart or heart valves.
Heart Valve
There are four valves in the heart: the tricuspid and the mitral valve, which lie between the atria and ventricles and the pulmonic and aortic valves which lie between the ventricles and the blood vessels leaving the heart. The heart valves help to maintain one-way blood flow through the heart.
Hemorrhaging
Heparin Lock (Heplock)
A small tube connected to a catheter in a vein in the arm for easy access.
Hibernating Myocardium
After a heart attack, some areas of heart muscle do not pump as they should. Some areas will have permanent damage. Other areas are able to return to their normal function if blood flow is returned to that area by medications or a procedure. Hibernating myocardium is heart muscle that is "resting" and may possibly return to normal function.
Hydration
Provision of fluids by any means to prevent dehydration.
Hydrogenation
A process used by food manufacturers to harden unsaturated liquid vegetable oils into saturated fats, in order to increase the shelf-life of a product or make it thicker in consistency.
Hypertrophic Cardiomyopathy (HCM)
In this condition, the muscle mass of the left ventricle enlarges or "hypertrophies."
