Types of Oxygen

There are many types of devices which provide an increased oxygen concentration to a person. The choice of device depends on the amount of oxygen needed.

Oxygen Concentrator

An oxygen concentrator takes up air from the surroundings and separates oxygen from it. This is provided to the patient by means of a nasal cannula. The flow rate can be set with a built in flow meter. An oxygen concentrator is good for people who require long term oxygen therapy (LTOT) because it provides a continuous supply and does not require refilling.

An oxygen concentrator can be plugged into a standard electrical outlet or powered with a battery. Battery powered portable oxygen concentration are easier to use. Portable oxygen concentrators are a convenient form of portable oxygen supply.

Oxygen Bar

An oxygen bar consumes air from the environment and increases the oxygen concentration in it by 30%. This is provided through a headset so that the user does not experience a dried or discomforted nose. An oxygen bar is a great device for individuals who need to be alerted, energized or relaxed. Anyone who is going through stress, does not exercise or has to bear environmental pollution can benefit from this.

Liquid Oxygen

Oxygen changes into a liquid state at extremely low temperatures. When this is warmed, it changes back into a gas, and can be delivered to people. Oxygen in the liquefied state is stored in a vessel, and can also be transferred to portable oxygen cylinders for temporary use. The disadvantage of this method is that tanks must be frequently refilled because liquid oxygen can evaporate.

Compressed Oxygen

Compressed oxygen is stored in a cylinder under high pressure, and provides constant flow. This is used when an occasional supply is needed during physical activities. Compressed oxygen tanks must be handled with extreme care because of the high pressure.
