通气 (tōngqì) — to ventilate
HSK 7 | verb | mechanical or assisted ventilation of the lungs in critical care settings
通气 (tōngqì)
通气 in clinical medicine refers to ventilation — the movement of air or respiratory gases into and out of the lungs, whether spontaneous or mechanically assisted. At the C2 level, it encompasses a spectrum from basic bag-mask ventilation to advanced mechanical ventilation strategies in ICU settings. It is a cornerstone concept in respiratory medicine, critical care, anesthesia, and emergency medicine.
Meanings
- verb to ventilate; to support or facilitate respiratory gas exchange in a patient

Usage Notes
通气 has both a general meaning (airflow/ventilation in buildings) and the precise clinical meaning in respiratory medicine. In clinical contexts it exclusively refers to pulmonary ventilation. Respiratory physiology uses the ventilation-perfusion ratio (通气血流比值, V/Q ratio) as a key index of lung efficiency, and its disruption is the basis for most causes of hypoxemia.
In ICU medicine, 机械通气 (mechanical ventilation) management is a highly specialized skill, and the parameters — tidal volume (潮气量), respiratory rate (呼吸频率), PEEP (呼气末正压) — must be meticulously titrated. Ventilator-induced lung injury (呼吸机相关肺损伤) is a recognized complication requiring lung-protective strategies.
Memory Hook
通 (to pass through/open) + 气 (air/breath) — "make air pass through": ensuring that air can flow freely through the airways and lungs.
