  2. Heliox - Wikipedia

    en.wikipedia.org/wiki/Heliox

    Heliox is a breathing gas mixture of helium (He) and oxygen (O 2).It is used as a medical treatment for patients with difficulty breathing because this mixture generates less resistance than atmospheric air when passing through the airways of the lungs, and thus requires less effort by a patient to breathe in and out of the lungs.

  3. Breathing gas - Wikipedia

    en.wikipedia.org/wiki/Breathing_gas

    A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...

  4. Medical gas therapy - Wikipedia

    en.wikipedia.org/wiki/Medical_gas_therapy

    Helium (He) is colorless, odorless, tasteless, and inert noble gas. Helium is second lightest gas after hydrogen. [10] Heliox has a similar viscosity to air but a significantly lower density (0.5 g/L versus 1.2 5g/L at STP). Flow of gas through the airways comprises laminar flow, transitional flow and turbulent flow.

  5. Hydrox (breathing gas) - Wikipedia

    en.wikipedia.org/wiki/Hydrox_(breathing_gas)

    Precautions are necessary when using hydrox, since mixtures containing more than four percent of oxygen in hydrogen are explosive if ignited. Hydrogen is the lightest gas (one quarter the atomic mass of helium or one half the molecular mass of helium) but still has a slight narcotic potential and may cause hydrogen narcosis.

  6. Asphyxiant gas - Wikipedia

    en.wikipedia.org/wiki/Asphyxiant_gas

    The risk of breathing asphyxiant gases is frequently underestimated leading to fatalities, typically from breathing helium in domestic circumstances and nitrogen in industrial environments. [ 12 ] The term asphyxiation is often mistakenly associated with the strong desire to breathe that occurs if breathing is prevented.

    The next day, after stopping by a smoke and vape shop, Bell was spotted in a nearby parking lot, inhaling an inflated blue balloon. “At one point, it looked like he was about to fall asleep.

  9. Helium dilution technique - Wikipedia

    en.wikipedia.org/wiki/Helium_dilution_technique

    The helium dilution technique is the way of measuring the functional residual capacity of the lungs (the volume left in the lungs after normal expiration). This technique is a closed-circuit system where a spirometer is filled with a mixture of helium (He) and oxygen.
