ventilation
The process or technical system for supplying a room or building with fresh air and removing stale air.
Eine gute Belüftung im Klassenzimmer ist wichtig für die Konzentration.
Good ventilation in the classroom is important for concentration.
'Die Belüftung' (ventilation) is the noun form of the verb 'belüften' (to ventilate). The verb is made up of the prefix 'be-' and the noun 'Luft' (air). It means to supply something with air.
Wir sollten den Raum gut belüften, bevor die Gäste kommen.
We should ventilate the room well before the guests arrive.
In everyday language, 'Belüftung' (ventilation) is often combined with adjectives like 'gut' (good), 'schlecht' (poor), or 'ausreichend' (sufficient). Typical verbs are 'für Belüftung sorgen' (to ensure ventilation) or 'die Belüftung verbessern' (to improve ventilation).
In fensterlosen Räumen ist eine mechanische Belüftung notwendig.
In windowless rooms, mechanical ventilation is necessary.
You can recognize the medical meaning from signal words such as 'künstlich' (artificial), 'medizinisch' (medical), 'Patient' (patient), or 'Lunge' (lung). In most cases, this refers to mechanical support for breathing.
Der Patient musste auf der Intensivstation künstlich belüftet werden.
The patient had to be artificially ventilated in the intensive care unit.

'die Atmung' and 'die Belüftung' both have to do with air, but they usually belong to different areas. 'Atmung' means the biological process in humans, animals, or other living beings. 'Belüftung' normally means that a room, a building, or technically also the lungs are supplied with air. The words can be confusing because both can appear in medical texts. In everyday language, you say 'Atmung' for a person. For rooms, buildings, or a technical air supply, you say 'Belüftung'.
Im Keller ist die Belüftung schlecht, deshalb riecht es dort feucht.
The ventilation in the basement is poor, so it smells damp there.
Die Ärztin kontrolliert die Atmung des Kindes.
The doctor checks the child's breathing.
