It is supplied to certain patients through face masks or little plastic tubes in the nose. These patients need oxygen usually because their lungs are not working well enough on their own to supply the needed oxygen from just regular air.
some of the patients in hospitals need a higher percentage of oxygen to help them breathe.
To get more oxygen into the space, and to ensure that it gets out when you open the tap.
Their immune Systems r weak and they need help breathing

Medical and industrial oxygen is typically made by liquefying and fractionating air which is 21% oxygen. Gas suppliers then ship the oxygen either in liquid form or as compressed gas in pressure cylinders. Hospitals typically have large liquid oxygen tanks which provide all the gaseous oxygen to the wall outlets via pipes. Additionally, there are pressure tanks of gaseous oxygen for portable and emergency use. However, there is some growth in molecular sieve technologies which can allow hospitals to filter nearly pure oxygen directly from the air.
Firefighters typically get oxygen tanks from their fire department or fire station. These tanks are filled with compressed oxygen and are essential for providing breathable air to firefighters in hazardous or smoke-filled environments.
Gas can be compressed easily.
Oxygen tanks are made to hold oxygen in a compressed, gaseous form so it can be available when needed for medical or industrial uses.
Mountaineers often take oxygen tanks when they climb high mountains such as Everest. The tanks contain oxygen gas that has been compressed into small volume. This can help reduce the effect of atmospheric pressure
The same way they do today, they took saltwater into tanks while underwater, evaporated out the salt and electrolyzed the oxygen out of it. They also carried tanks of compressed air in the submarine.
Compressed oxygen--oxygen that is stored as a gas in a tank.
Air tanks were invented to hold compressed air.
A oxygen concentrator is a device providing oxygen therapy to a patient at minimally to substantially higher concentrations than available in ambient air.They are used as safer,less expensive, and more convenient alternative to tanks of compressed oxygen.
actually compressed oxygen does actually have weight.
Compressed gases are used as fuels, in industry, laboratories, hospitals, etc.
Compressed oxygen gas stored in tanks is lightweight enough to be carried around in a day to day environment. It is vitally important to take safety into account when carrying compressed flamable materials around.
