ventiliator

Ventiliator is a term that can refer to several different devices related to air movement and ventilation. Most commonly, it refers to a fan, an electrical device that uses rotating blades to move air. These fans are used in a wide variety of applications, including cooling personal spaces, circulating air in rooms, and in industrial settings for process cooling or exhaust.

In a medical context, a ventiliator is a machine that assists or completely takes over the function of breathing for a patient. These life-support devices are used in hospitals, particularly in intensive care units, for individuals who are unable to breathe adequately on their own due to illness, injury, or surgery. Medical ventiliators deliver a controlled mixture of air and oxygen into the lungs and remove carbon dioxide.

The term can also be used more broadly to describe any apparatus designed to ventilate a space, which means to provide fresh air and remove stale or polluted air. This can encompass simple passive vents in buildings or more complex mechanical ventilation systems that are integrated into HVAC (heating, ventilation, and air conditioning) units. The specific meaning of "ventiliator" depends heavily on the context in which it is used.
