同義詞
  • oxygen deficiency

    less technical, used in both medical and general contexts

  • anoxia

    more severe — means complete lack of oxygen, not just insufficient

  • hypoxemia

    more specific — refers to low oxygen in the blood, not necessarily in the tissues

用法筆記

Frequently paired with a severity or location adjective: acute hypoxia, chronic hypoxia, cerebral hypoxia. The term hypoxemia refers specifically to low oxygen in the blood, while hypoxia can refer to low oxygen in the tissues.

常見錯誤

❌The patient suffered from hypoxemia in her brain.
✅The patient suffered from cerebral hypoxia.
💡hypoxemia is low oxygen in the blood; hypoxia in the brain tissue is cerebral hypoxia.

collocation: zones of hypoxia

同義詞
  • oxygen depletion

    focuses on the process of oxygen being removed, rather than the resulting condition

  • deoxygenation

    technical term for the process of oxygen being removed from water

  • dead zone

    informal term for a large area of hypoxia in water, especially where marine life cannot survive

用法筆記

Common in ecology and environmental science; often paired with zone, area, or event (e.g. hypoxia zone, hypoxic event). The adjective hypoxic describes the affected area.

常見錯誤

❌The river had hypoxia because it was too warm.
✅The river had a zone of hypoxia because pollution caused algae to use up the oxygen.
💡hypoxia in the environmental sense is not simply warm water; it refers to a measurable lack of dissolved oxygen.
