stagnant anoxia
Học thuậtThân thiện
Definition
Noun: - A type of oxygen deficiency in tissues: Stagnant anoxia is a medical condition characterized by an inadequate supply of oxygen to body tissues. This deficiency is not caused by a lack of oxygen in the blood itself, but rather by an abnormally slow or stagnant blood flow, which fails to deliver oxygenated blood to the tissues at a sufficient rate.
Usage
- Medical/Clinical Context: This term is used specifically in medical fields such as physiology, cardiology, and emergency medicine to describe a cause of tissue hypoxia.
- The patient's low blood pressure led to stagnant anoxia in the extremities.
- Congestive heart failure is a common cause of stagnant anoxia.
Advanced Usage
- Pathophysiological Mechanism: The term is used to distinguish this cause of oxygen deprivation from other types, such as hypoxic anoxia (low oxygen in blood) or anemic anoxia (low oxygen-carrying capacity of blood). The key factor is impaired circulation.
- In shock, stagnant anoxia can occur even if the blood is fully oxygenated.
Variants and Related Words
- Anoxia (n): A broad term for a severe deficiency of oxygen supply to tissue.
- Hypoxia (n): A condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level (a broader term that includes less severe states than anoxia).
- Ischemia (n): An inadequate blood supply to an organ or part of the body, often leading to stagnant anoxia.
- Stagnant (adj): Not flowing or moving; often describing sluggish blood flow in this context.
Synonyms
- Circulatory anoxia: A direct synonym emphasizing the cause.
- Hypoperfusion-related hypoxia/anoxia: A more descriptive synonym focusing on the mechanism of low blood flow.
Related Phrases/Compounds
- Stagnant anoxia of the brain: Specifies the condition affecting cerebral tissue.
- Local stagnant anoxia: Refers to the condition affecting a specific area of the body due to localized poor circulation.
Noun
- anoxia resulting from slow peripheral circulation (such as follows congestive cardiac failure)
