mechanical ventilation

ventilation + support

用法筆記

Medical context. Distinguish from 'respiration', which refers to the body's own gas exchange at the cellular level; ventilation is the mechanical process of moving air in and out of the lungs. Often preceded by 'mechanical' or 'artificial' when a machine is used.

常見錯誤

❌The patient needs ventilation because he broke his arm.
✅The patient needs ventilation because his lungs cannot move air in and out on their own.
💡ventilation in this sense is only about breathing assistance, not general medical care.

同義詞

    Less formal; 'airing of grievances' is a common phrase

  • expression

    Broader; covers any form of communication, not just forceful or pent-up opinions

  • outlet

    Focuses on the channel or release mechanism rather than the act itself

反義詞
  • suppression

    Deliberately holding back an opinion or feeling

文法句型

ventilation + of + opinion/concern/feeling

用法筆記

Figurative and fairly formal. Typically followed by 'of' + an abstract noun (anger, frustration, concern, opinion). The image is that of letting air out — the speaker 'vents' a feeling so it no longer builds up pressure. This sense is less common than senses 1 and 2 in everyday speech.

常見錯誤

❌I need ventilation of my new bicycle.
✅I need ventilation of my concerns about the new policy.
💡this sense only works for opinions, feelings, or ideas, not physical objects.
