Think: 'VENT' for air and '-ILATOR' like 'accelerator'—a device that accelerates or controls the flow of air.
Conceptual Metaphor
LUNGS AS BELLOWS / LIFE AS A MACHINE.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'кондиционер' (air conditioner). A ventilator moves air; an air conditioner cools it. The medical device is 'аппарат искусственной вентиляции лёгких' (ИВЛ).
Common Mistakes
- Using 'ventilator' to mean a simple fan (more common: 'extractor fan' or 'vent'). Confusing 'ventilator' (medical device) with 'respirator' (which can also mean a face mask filter).

FAQ
Frequently Asked Questions
No. An oxygen tank supplies concentrated oxygen. A ventilator is a machine that physically pushes air (which may contain oxygen) in and out of the lungs. A patient can use one or both.
In very informal medical slang, sometimes. However, 'on a ventilator' or 'on life support' is the standard, clear terminology.
In modern medical usage, they are often used interchangeably for the breathing machine. Technically, a 'respirator' can also refer to a protective mask (like an N95). In engineering, a ventilator moves air for comfort, while a respirator is for filtration.
No, it is typically used for acute, short-term support during illness or surgery. Some patients with chronic conditions may require long-term ventilation, but the goal is often to wean them off the machine as they recover.
