anemic hypoxia
Học thuậtThân thiện
Definition
- Noun:
- A type of hypoxia caused by insufficient hemoglobin: "Anemic hypoxia" refers to a condition where the blood's ability to carry oxygen is reduced due to a lower-than-normal concentration of hemoglobin, the oxygen-carrying protein in red blood cells.
Usage
- "Anemic hypoxia" is a medical term used to describe a specific physiological state. It is typically used in clinical, scientific, or educational contexts.
- It is often discussed in contrast to other forms of hypoxia, such as hypoxic hypoxia (low oxygen in the air) or stagnant hypoxia (poor blood circulation).
Examples
- Noun:
- The patient's severe iron deficiency led to anemic hypoxia.
- Anemic hypoxia can be a complication of chronic kidney disease.
Advanced Usage
- The term is used to specify the underlying cause of oxygen delivery failure to tissues, distinguishing it from problems with oxygen uptake in the lungs or blood flow.
- It can be part of a differential diagnosis when a patient presents with symptoms of tissue oxygen deprivation (like shortness of breath or fatigue) but has normal arterial oxygen levels.
Variants and Related Words
- Hypoxia (n): A broad term for a deficiency in the amount of oxygen reaching the tissues.
- Anemia (n): A condition marked by a deficiency of red blood cells or hemoglobin, which is the most common cause of anemic hypoxia.
- Ischemic hypoxia: Often used similarly to "stagnant hypoxia," referring to hypoxia caused by inadequate blood flow.
Synonyms
- Hemoglobin-deficiency hypoxia: A more descriptive synonym.
- Anoxemia (in some specific contexts, though this more generally means lack of oxygen in the blood).
Related Phrases/Concepts
- Oxygen-carrying capacity: The maximum amount of oxygen the blood can transport, which is directly reduced in anemic hypoxia.
- Functional anemia: A state that can lead to anemic hypoxia, where hemoglobin is present but impaired (e.g., carbon monoxide poisoning).
Noun
- hypoxia resulting from a decreased concentration of hemoglobin
