    Most commercial aircraft that operate at high flight altitudes are pressurized at a maximum cabin altitude of approximately 8,000 feet. On most pressurized aircraft, if cabin pressurization is lost when the aircraft is flying at an altitude above 4,267 m (14,000 feet), compartments containing the oxygen masks will open automatically, either above or in front of the passenger and crew seats ...

    Bottled oxygen, more broadly known as high pressure compressed oxygen, medical oxygen, and aviator's oxygen, is oxygen in small, portable, high-pressure storage cylinders. For aviation, the weight of the cylinder is usually not critical, and the choice of material may be affected by economic considerations such as purchase price and useful ...

    A pocket mask, pocket face mask or CPR mask, is a compact device used to safely deliver rescue breaths during a cardiac arrest or respiratory arrest by providing a sealed connection to the respiratory tract that is isolated from direct contact with the recipient's exhalations by a filter or non-return valve. portable gaseous oxygen system

    en.wikipedia.org/wiki/Oxygen_mask

    An oxygen mask is a mask that provides a method to transfer breathing oxygen gas from a storage tank to the lungs. Oxygen masks may cover only the nose and mouth (oral nasal mask) or the entire face (full-face mask). They may be made of plastic, silicone, or rubber. In certain circumstances, oxygen may be delivered via a nasal cannula instead ...

    According to Adrian, pilots regularly lost consciousness during high-altitude dogfights, and needed "an oxygen delivery system with a demand valve responsive to altitude and activity". [4] Millikan built the device for monitoring the state of pilot's organism in flight (the Millikan oximeter ) in 1940 and presented it to the American ...

    Hypobaric chamber at the Biopol'H, in Catalonia (), used with patients and athletes who need treatment or training with reduced atmospheric pressure. A hypobaric chamber, or altitude chamber, is a chamber used during aerospace or high terrestrial altitude research or training to simulate the effects of high altitude on the human body, especially hypoxia (low oxygen) and hypobaria (low ambient ...
