  2. Intra-aortic balloon pump - Wikipedia

    en.wikipedia.org/wiki/Intra-aortic_balloon_pump

    The intra-aortic balloon pump (IABP) is a mechanical device that increases myocardial oxygen perfusion and indirectly increases cardiac output through afterload reduction. It consists of a cylindrical polyurethane balloon that sits in the aorta , approximately 2 centimeters (0.79 in) from the left subclavian artery . [ 1 ]

    en.wikipedia.org/wiki/Adrian_Kantrowitz

    The intra-aortic balloon pump was invented by Kantrowitz, working in conjunction with his brother, Arthur Kantrowitz. Inserted through the patient's thigh, it was directed into the aorta, and alternately expanded and contracted in order to reduce strain on the heart. Based on Kantrowitz's theory of "counterpulsation", the device inflated the ...

  4. Cardiogenic shock - Wikipedia

    en.wikipedia.org/wiki/Cardiogenic_shock

    An intra-aortic balloon pump is a device placed by a cardiac surgeon into the descending aorta. It consists of a small balloon filled with helium that helps the heart to pump blood by inflating during diastole (the resting phase of the cardiac cycle) and deflating during systole (the contracting phase of the cardiac cycle). [16]

  5. Suicide bag - Wikipedia

    en.wikipedia.org/wiki/Suicide_bag

    In 2015 author and right-to-die advocate Derek Humphry reported that Worthington Industries, the world's largest manufacturer of disposable helium cylinders, had announced that their helium cylinders will guarantee only 80% helium, with up to 20% air, making them inappropriate for use with a suicide bag in Humphry's opinion. [23]

  6. Lifting gas - Wikipedia

    en.wikipedia.org/wiki/Lifting_gas

    Hydrogen and helium are the most commonly used lift gases. Although helium is twice as heavy as (diatomic) hydrogen, they are both significantly lighter than air. The lifting power in air of hydrogen and helium can be calculated using the theory of buoyancy as follows: Thus helium is almost twice as dense as hydrogen.

  7. Helium compounds - Wikipedia

    en.wikipedia.org/wiki/Helium_compounds

    Helium is the smallest and the lightest noble gas and one of the most unreactive elements, so it was commonly considered that helium compounds cannot exist at all, or at least under normal conditions. [1] Helium's first ionization energy of 24.57 eV is the highest of any element. [2]

  8. Liquid helium - Wikipedia

    en.wikipedia.org/wiki/Liquid_helium

    Liquid helium is a physical state of helium at very low temperatures at standard atmospheric pressures.Liquid helium may show superfluidity.. At standard pressure, the chemical element helium exists in a liquid form only at the extremely low temperature of −269 °C (−452.20 °F; 4.15 K).

  9. Ballon Generali - Wikipedia

    en.wikipedia.org/wiki/Ballon_Generali

    The Ballon Generali is a tethered helium balloon, used as tourist attraction and as an air quality awareness tool. Installed in Paris since 1999 in the Parc André-Citroën, it was created and developed by the French company Aerophile SAS for the celebration of the year 2000. The balloon has lofted more than 500,000 passengers into the sky ...
