  2. Lifting gas - Wikipedia

    en.wikipedia.org/wiki/Lifting_gas

    A balloon can only have buoyancy if there is a medium that has a higher average density than the balloon itself. Balloons cannot work on the Moon because it has almost no atmosphere. [14] Mars has a very thin atmosphere – the pressure is only 1 ⁄ 160 of earth atmospheric pressure – so a huge balloon would be needed even for a tiny lifting ...

    en.wikipedia.org/wiki/Intra-aortic_balloon_pump

    An 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]

    Based on Kantrowitz's theory of "counterpulsation", the device inflated the balloon with helium gas when the heart relaxed and deflated it when the heart pumped blood. [6] [7] The pump did not require surgery and could be inserted using local anesthetic in an emergency room or at a patient's bedside. The device was first used in August 1967 to ...

  8. Inflatable - Wikipedia

    en.wikipedia.org/wiki/Inflatable

    A balloon is an inflatable flexible filled with air and also gas, such as helium, hydrogen, nitrous oxide or oxygen. Modern balloons can be made from materials such as latex rubber , polychloroprene , or a nylon fabric, while some early balloons were made of dried animal bladders [ citation needed ] .

  9. 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.
