oxygen canisters
Portable air tanks
Oxygen canisters are portable containers holding compressed or liquid oxygen for breathing.
They supply supplemental oxygen to people with respiratory conditions, mountaineers at high altitude, divers, or pilots.
In emergencies, aircraft deploy oxygen masks connected to canisters: The oxygen canisters dropped from the overhead compartment.
Smaller canisters are marketed to athletes and hangover sufferers with dubious benefit.
