Oxygen Concentrator


Oxygen is present in air with a concentration of about 21%. Under atmospheric conditions, oxygen is in a gaseous state, odorless, colorless or tasteless. It is a highly reactive substance that reacts with almost all elements except inert gases.


Gaseous oxygen generation


Gaseous oxygen can be obtained by gas separation using adsorption (PSA) or fractional distillation of liquefied gas using cryogenic plants.


What is an oxygen concentrator for?


Often, oxygen therapy is needed by a person to maintain normal body functions in case he becomes ill.


Oxygen is often used in diseases such as:


  • heart failure,
  • chronic obstructive pulmonary disease,
  • bronchial asthma and others.



In such diseases, the patient is attached for the necessary time to an oxygen concentrator for treatment. It should be noted that the oxygen concentrator emits oxygen with a concentration of 93%.

Depending on the size, method of power supply and productivity (the amount of oxygen released per minute) they are divided into stationary (used in hospitals and clinics) and portable (at home for personal use).


Using a hub in everyday life


Such use has become relevant and in demand recently. Environmental pollution has affected the health of people in cities and megacities. A few minutes of oxygen therapy will fill the body with clean air and launch its functions in full force. An oxygen concentrator is an affordable way to maintain health at home.


How to use a medical oxygen concentrator


The duration of therapy can be from 1 hour to 24 hours, it all depends on the condition of the patient, the disease and the recommendations of the doctor.

For complex diseases and moderate severity, the device that produces at least 90% concentrated oxygen from 5 liters per minute will be the best option. A 5 liter concentrator is considered portable. Its low weight allows a person to fully move around and lead a normal lifestyle. The length of the hose does not limit movement and provides maximum comfort. Oxygen concentrators are equipped with one or two batteries that operate without recharging for several hours. Available control functions are easy to use.


Choosing an Oxygen Concentrator


For hospital conditions, 10 liter concentrators are suitable. 10 liters is not the size of the apparatus, but the amount of oxygen that the concentrator can produce per minute! Oxygen concentrators are characterized by increased productivity and efficiency. These properties make it possible to provide the body with oxygen around the clock for severe diseases, for connecting the device to breathing equipment.


An important factor when buying a device is the published noise level. A long period of treatment in conditions of increased noise can cause irreparable harm to mental health. Therefore, it is important that the sound is as quiet as possible.


An important detail in the design of oxygen concentrators is their equipment with audible warning signals and automatic operation settings. We are talking about a timer and sound signals that inform about the end of the operating time, discharge of the device, malfunctions and other things.



The options for oxygen concentrators vary by model and manufacturer.


General characteristics of oxygen concentrators


  • From 1 to 10 liters of oxygen per minute are produced.
  • Low noise compressor.
  • The case is made of durable plastic.
  • Touch or button controls.
  • Timer from 15 to 180 minutes.
  • Overheat protection.
  • Sleep timer
  • Sound signal in the absence of power supply or other problems.
  • Four wheels, a convenient bag or handle for free movement.


An oxygen concentrator to buy and not be disappointed will allow a competent approach to the choice. It is necessary to evaluate where it will be used, who its patients will be, what settings you need to use. The price of oxygen concentrators depends on the options and capabilities of the device.


What affects the price of a portable hub:


  • Oxygen performance
  • Additional handsets
  • The presence of additional batteries,
  • Humidifier in the design,
  • The amount of energy consumed,
  • The number of patients who can simultaneously use.
