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)
When Tenzing and 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]
