    en.wikipedia.org/wiki/Gooseneck_(piping)

    Gooseneck vent with check valve being repainted. A gooseneck (or goose neck) is a 180° pipe fitting at the top of a vertical pipe that prevents entry of water. Common implementations of goosenecks are ventilator piping or ducting for bathroom and kitchen exhaust fans, ship holds, landfill methane vent pipes, or any other piping implementation exposed to the weather where water ingress would ...

    The jacket ventilator, also known as a poncho or raincoat ventilator, is a lighter version of the iron lung or the cuirass ventilator, constructed of an airtight material (such as plastic or rubber) arranged over a light metal or plastic frame, or screen, and depressurized and repressurized by a portable ventilator.

    It worked out of water, but when he tested the aqualung in the river Marne air free-flow ed from the regulator before it could be breathed when the mouthpiece was above the regulator. After that, he had the second breathing tube fitted. Even with both tubes fitted, raising the mouthpiece above the regulator increases the delivered pressure of ...

    It is generally regarded, based on animal models and human studies, that volutrauma is the most harmful aspect of mechanical ventilation. [2] [3] [4] This may be regarded as the over-stretching of the airways and alveoli. [citation needed] During mechanical ventilation, the flow of gas into the lung will take the path of least resistance.

    Intensive-care ventilators—These ventilators are larger and usually run on AC power (though virtually all contain a battery to facilitate intra-facility transport and as a back-up in the event of a power failure). This style of ventilator often provides greater control of a wide variety of ventilation parameters (such as inspiratory rise time).

    An open-source ventilator is a disaster-situation ventilator made using a freely-licensed design, and ideally, freely-available components and parts. Designs, components, and parts may be anywhere from completely reverse-engineered to completely new creations, components may be adaptations of various inexpensive existing products, and special ...

    Without breathing gas the diver will die in minutes. Running out of gas is a major contributor to diving accidents. Many scuba accidents start in some other way and culminate in running out of gas. The main reasons for running out of scuba gas are: [5] [6] [7] failing to monitor consumption of the gas - not watching the contents pressure gauge

  9. Artificial ventilation - Wikipedia

    en.wikipedia.org/wiki/Artificial_ventilation

    Artificial ventilation or respiration is when a machine assists in a metabolic process to exchange gases in the body by pulmonary ventilation, external respiration, and internal respiration. [1] A machine called a ventilator provides the person air manually by moving air in and out of the lungs when an individual is unable to breathe on their own.
