James T. Kirk, Spock and Leonard McCoy with respirators.

A respirator, life support mask or breathing apparatus was a device that allowed the user to breathe for a short period in unhealthy environments.

Respirators were used for some species to serve aboard Federation starships, and helped humans visit some alien planets.

It was also used as a medical technology, often in sickbay.


Human field equipmentEdit

A life support mask filtered out harmful components from most atmospheric conditions. An associated power pack and fresh filter provided about 12 hours of service. (FASA RPG module: Spacelanes: The Magazine of Interstellar Trade)

It adjusted atmospheric pressurize and temperature to class M conditions for the wearer. Commercial variants were available to the public. (FASA RPG modules: Trader Captains and Merchant Princes, 1st edition, 2nd edition)
