Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like 'оксигенатор' without context—it's understood but sounds very technical. The concept is better explained as 'аппарат для оксигенации крови/воды'.
Common Mistakes
- Using 'oxygenator' to mean the process of oxygenating (the correct noun is 'oxygenation').
- Confusing 'oxygenator' with 'oxygen tank' (which stores oxygen, rather than adding it to another medium).

FAQ
Frequently Asked Questions
Its primary purpose is to add oxygen to and remove carbon dioxide from a fluid, most critically blood during major surgery or water in aquaculture.
No, it is a specialised technical term used almost exclusively in medical, engineering, and environmental fields.
No, the verb form is 'to oxygenate'. An 'oxygenator' is the noun for the device that performs that action.
An aerator primarily mixes air with water, which indirectly adds oxygen. An oxygenator is specifically designed to maximise the transfer and dissolution of oxygen molecules into the medium, often using pure oxygen or specialised membranes.
