ischemic anoxia
Học thuậtThân thiện
Definition
Noun: - A type of oxygen deficiency in tissues: Specifically, a condition of anoxia (severe lack of oxygen) caused by inadequate blood flow to a part of the body, resulting in insufficient oxygen delivery to the tissues.
Usage
This is a medical term used to describe a pathological state where tissue hypoxia is caused by reduced blood circulation, not by a lack of oxygen in the blood itself. It is often associated with conditions that impair blood flow.
Examples
- Noun:
- The patient developed ischemic anoxia in the limb due to a blocked artery.
- Prolonged ischemic anoxia can lead to irreversible tissue damage and necrosis.
Advanced Usage
- Pathophysiological Context: The term is used to distinguish anoxia caused by circulatory failure (ischemic) from other types, such as anemic anoxia (low hemoglobin) or hypoxic anoxia (low oxygen in arterial blood).
- In cardiogenic shock, systemic ischemic anoxia becomes a critical concern.
Variants and Related Words
- Ischemia (n): A restriction in blood supply to tissues.
- Myocardial ischemia is a common cause of chest pain.
- Anoxia (n): An absence or severe deficiency of oxygen reaching the tissues.
- Cerebral anoxia can result from drowning.
- Hypoxia (n): A deficiency in the amount of oxygen reaching the tissues (less severe than anoxia).
- The pilot experienced hypoxia at high altitude.
Synonyms
- Stagnant anoxia: An older, synonymous term emphasizing the role of slowed or stagnant blood flow.
- Circulatory anoxia: A descriptive synonym highlighting the circulatory cause.
Related Phrases
- Ischemic injury: Damage caused by ischemia.
- The goal of treatment is to minimize ischemic injury to the brain.
- Anoxic brain injury: Brain damage resulting from a complete lack of oxygen.
Notes
This is a compound noun formed from the adjective "ischemic" (relating to ischemia) and the noun "anoxia." It is primarily used in clinical, medical research, and pathological contexts.
Noun
- anoxia resulting from slow peripheral circulation (such as follows congestive cardiac failure)
