  2. Gas duster - Wikipedia

    en.wikipedia.org/wiki/Gas_duster

    A gas duster, also known as tinned wind, compressed air, or canned air, is a product used for cleaning or dusting electronic equipment and other sensitive devices that cannot be cleaned using water. This type of product is most often packaged as a can that, when a trigger is pressed, blasts a stream of compressed gas through a nozzle at the top.

  3. Airway management - Wikipedia

    en.wikipedia.org/wiki/Airway_management

    Prevention techniques focus on preventing airway obstruction by the tongue and reducing the likelihood of aspiration of stomach contents or blood. The head-tilt/chin-lift and jaw-thrust maneuvers are useful for the former while the recovery position is useful for the latter. If head-tilt/chin-lift and jaw-thrust maneuvers are performed with any ...

  4. Compressed air - Wikipedia

    en.wikipedia.org/wiki/Compressed_air

    An early major application of compressed air was in the drilling of the Mont Cenis Tunnel in Italy and France in 1861, where a 600 kPa (87 psi) compressed air plant provided power to pneumatic drills, increasing productivity greatly over previous manual drilling methods. Compressed-air drills were applied at mines in the United States in the 1870s.

  5. Dust-Off - Wikipedia

    en.wikipedia.org/wiki/Dust-Off

    Dust-Off is a brand of dust cleaner (refrigerant-based propellant cleaner, which is not compressed air and incorrectly called "canned air"). The product usually contains difluoroethane; although some use tetrafluoroethane and tetrafluoropropene as a propellant. It is used to blow particles and dust from computer, keyboards, photography ...

  6. Cabin pressurization - Wikipedia

    en.wikipedia.org/wiki/Cabin_pressurization

    The most common source of compressed air for pressurization is bleed air from the compressor stage of a gas turbine engine; from a low or intermediate stage or an additional high stage, the exact stage depending on engine type. By the time the cold outside air has reached the bleed air valves, it has been heated to around 200 °C (392 °F). The ...

    Examples include rehab & intensive outpatient therapy are examples of a few short-term preventions. Tertiary prevention involves an individual such as one suffering from substance use to receive treatment such as rehab or an intensive therapy but the process of recuperating will be longer due to the intense amount of intake within the body.

  8. Vibration isolation - Wikipedia

    en.wikipedia.org/wiki/Vibration_isolation

    A source of compressed air is required to maintain them. Air springs are rubber bladders which provide damping as well as isolation and are used in large trucks. Some pneumatic isolators can attain low resonant frequencies and are used for isolating large industrial equipment. Air tables consist of a working surface or optical surface mounted ...

    Oil getting into the air and partially oxidising in the compressor cylinder, like in a diesel engine, due to worn seals and use of unsuitable oils, or an overheated compressor. [25] Adequate maintenance of the compressor. Use of correct oil rated for breathing air compressor lubrication. [25] Ensure compressor running temperature is within ...
