An example of bottled oxygen

Bottled oxygen is oxygen in bottles, a terminology especially for high-altitude climbing. Bottled oxygen may also be for a breathing gas, especially for scuba or surgeries. (see also Diving cylinder and Oxygen tank)

When Tenzing Norgay and Edmund Hillary made the first successful summit of Mount Everest in 1953 they used bottled oxygen.[1] It was noted for its ability to increase the user's appreciation of the surroundings.[1]

Running out of bottled oxygen was noted as a factor in the 1979 deaths of Ray Genet and Hannelore Schmatz on Mount Everest.[2]

By the 21st century one of the popular oxygen systems on Mount Everest used carbon-fiber aluminum bottles, with a 3 liter bottling of oxygen weighing 7 pounds when filled up at 3000 psi.[3]
